Chapter 2: Hardware Installation
Considerations When Installing Acuvim 3
ELECTRIC SHOCK HAZARD
SAFETY WARNING• Installation of the Acuvim3 must be performed by a qualified personnel only, who follow

standard safety precautions through the installation procedures. Those personnel must haveappropriate training and experience with high voltage electrical devices. Appropriate safety
gloves, safety glasses and protective clothing are strongly recommended.

• During normal operation, dangerous voltage levels may flow through many parts of the

Acuvim 3, including terminals, and any connected current transformers (CTs) and potential
transformers (PTs), all inputs and outputs(I/O) modules and their circuits. All primary andsecondary circuits can, at times, produce lethal voltage and current levels. AVOID contact withany current-carrying surfaces.

• The Acuvim 3 and its I/O output channels are NOT designed as primary protection devices
and shall NOT be used as primary circuit protection or in an energy limiting capacity. The

Acuvim 3 and its I/O output channels can only be used as secondary protection. AVOID using
the Acuvim3 under situations where failure of the Acuvim 3 may cause injury or death. AVOID
using the Acuvim 3 for any application where the risk of fire may occur.

• All Acuvim 3’s terminals shall be inaccessible after installation.
• Do NOT perform dielectric (HIPOT) test to any inputs, outputs, or communication terminals.
High voltage testing may damage electronic components of the Acuvim 3.

• Applying more than the maximum voltage the Acuvim 3 and/or its modules can withstand will

permanently damage the Acuvim 3 and/or its modules. Please refer to the specifications for all
devices before applying voltages.

• When removing Acuvim 3 for service, use shorting blocks and fuses for voltage leads andpower supply to prevent hazardous voltage conditions or damage to CTs. CT grounding is
optional.

• Accuenergy recommends using a dry cloth to wipe the Acuvim 3.
NOTE: IF THE EQUIPMENT IS USED IN A MANNER NOT SPECIFIED BY THE MANUFACTURER, THE
PROTECTION PROVIDED BY THE EQUIPMENT MAY BE IMPAIRED.

4 Digital Inputs (DI)• Each digital input can be used in pulse counter or digital status mode.
• Digital status mode enables the DI to detect remote signals. The Acuvim 3 will log the time/
date of each detected event and store it in the SOE (sequence of events) log.

• Pulse counter mode enables the DI to count digital pulses.
• Terminals DI1 to DIC are the digital input ports, where DIC is the common terminal for DI1 to
DI4 circuits.

2 Relay Outputs (RO)• The relay outputs can be used in two different modes, control mode or alarm mode, where
both relay channels will operate in the same mode.

• Control mode allow users to configure the relay to work in either latch mode (ON/OFF

remains in current state until explicit instructions to change states) or momentary mode
(ON/OFF for a certain time interval).

• Alarm mode will turn the relay ON/OFF based on a status configured on the alarm in the
Acuvim 3.

• Terminals RO1 to ROC are the relay output ports, where ROC is the common terminal for RO1
and RO2 circuits.

2 Analog Inputs (AI)• Can detect input analog voltage or analog current.
• When it detects input analog voltage, the range of voltage is from 0 to 5V or from 1 to 5V.
• When it detects input analog current, the range of current is from 0 to 20mA or from 4 to
20mA.

•

Terminals AI1+ to AI2- are analog input terminals.

NOTE: There are four AXM-IO3 module types to choose from. Each AXM-IO3 module can only
read input from one type of analog signal upon purchase. Either 0 to 5V, 1 to 5V, 0 to 20mA, or 4
to 20mA types are available.

4.3.3.4 Four Quadrant Energy
For a power system, the relationship between apparent power, active power and reactive power isoften defined as:
Where reactive power (Q, in Var units) is plotted on the ordinate axis, and active power (P, in
Watts) is plotted on the abscissa. This coordinator has been defined as a four-quadrant system
and indicates the power-flow concept of energy. The flow of power will result in the registration ofenergy in quadrants that correspond to the power vector location.

Crest Factor: The ratio between either the peak current or voltage and the RMS value.
K-Factor: A measure of the heating effect caused by current harmonics, which helps determine
the linearity of a load. A K-factor value of 1 indicates that the load is linear, and there are no
harmonics present. However, a K-factor value greater than one means that the load is not linear,and there is a higher heating effect caused by the harmonics in the system.

Nominal Voltage: The original voltage value measured across its primary winding. For example, if
the potential transformer’s (PT) ratio is 600V:120V, the nominal voltage should be set to 600V. The
default nominal voltage is 120V.
Nominal Current: The original current value measured across its primary winding. For example,
if the current transformer’s (CT) ratio is 300A:5A, the nominal current should be set to 300A. The
default nominal current is 5A.

PT and CT

Figure 4-42 PT/CT Ratios Settings Window

PT Input: If using potential transformers with the Acuvim 3 at the voltage input, this setting refers
to the primary side rating of the transformer. The range is from 50-500000. If PTs are not being
used with the Acuvim 3, this setting can be left as the default, which is 120. PT Input must be an
integer.
PT Output: If using potential transformers with the Acuvim 3 at the voltage input, this settingrefers to the secondary side rating of the transformer. The range is from 50-600. If PTs are notbeing used with the Acuvim 3, this setting can be left as the default, which is 120.0. PT Output
must be an integer.
CT Input: The primary side rating of the current transformers being used with the Acuvim 3. For
example, if the CTs being used have a ratio of 200:5A, the CT Input setting should be configured
as 200. The allowable range for the CT Input setting is from 1 to 50000. The default CT Input valueis 5. CT Input must be an integer.
CT Output: The secondary output of the current transformers. By default, the CT Output setting
is already configured based on the current input type for the Acuvim 3 Acuvim 3. For example, theCT Output value will be configured to 5 for a 5A current input Acuvim 3, 333 for a 333mV current
input Acuvim 3, and RCT for an RCT current input Acuvim 3.
In Method: Readings on Acuvim 3 can be set as either calculated or measured. When it is inmeasured mode, physical wiring needs to be applied. If it is in calculated mode, the calculation isbased on KCL, the neutral current is the vector sum of the three individual live currents.

PF Convention IEC: Power factor is dependent on the direction of the real power flow.
PF Convention IEEE: Power factor is dependent on the nature of the load (i.e. capacitive,
inductive).
Reactive Power Calculation Method: There are two ways to calculate reactive energy (power).
True Method: This method uses the Budeanu Concept to calculate the True reactive Power. Thismethod generally uses the harmonic components to do the calculation instead of using the power
vector triangle method. The most common definition of reactive power is Budeanu’s definition,
given by following expression for single phase circuit:

Where

Budeanu proposed that apparent power consists of two orthogonal components, active power
and nonactive power, which are divided into reactive power and distortion power:

Where

Generalized Method: The method uses Fryze’s concept to calculate the Generalized reactive
power. This method separates instantaneous current into two components, active and reactive
currents. Active power and reactive power calculated as:

Nominal Voltage: The original voltage value measured across its primary winding. For example,
all power quality event thresholds and hysteresis related to voltage are calculated based on thecustomized nominal current.
Nominal Current: The original current value measured across its primary winding. For example,
all power quality event thresholds and hysteresis related to current are calculated based on thecustomized nominal current.

6.1.1 Voltage Sag Detection
Voltage Sag: Acuvim 3 detects voltage sag by assessing the half-cycle voltage RMS. A voltage
sag event starts when the voltage RMS of any channel falls below the defined threshold andends when the voltage RMS of all measured channels is equal to or above the threshold plus the
specified hysteresis voltage.
Threshold and Hysteresis: Users can configure the threshold percentage within the range of
10% to 90% and the hysteresis percentage within the range of 1% to 10% to precisely define theconditions for detecting voltage sag events.
Example: When a user defines a nominal voltage of 120V and configures the voltage sag
threshold to 50% with a hysteresis of 1%, a voltage sag event record will commence if any oneof the half-cycle voltage RMS values drops below 60V. The voltage sag event record will conclude
when all the half-cycle voltage RMS values have increased to equal or exceed 61.2V.

V: 1.0.3 Revised: September 2024
www.accuenergy.com

149

Acuvim 3 Series Power Meter
6.1.2 Voltage Swell Detection
Voltage Swell: Acuvim 3 detects voltage swell by examining the half-cycle voltage RMS. A voltage
swell event initiates when the half-cycle voltage RMS of any channel exceeds the specified
threshold and concludes when the half-cycle voltage RMS on all measured channels equals or falls
below the threshold minus the set hysteresis voltage.
Threshold and Hysteresis: Users can customize the threshold percentage within the rangeof 110% to 150% and set the hysteresis percentage within the range of 1% to 10% to precisely
define the criteria for detecting voltage swell events.
Example: When a user defines a nominal voltage of 120V and configures the voltage swellthreshold to 150% with a hysteresis of 1%, a voltage swell event record will begin if any one of thehalf-cycle voltage RMS values surpasses 180V. The voltage swell event record will end when all thehalf-cycle voltage RMS values have dropped to equal or fall below 178.8V.

6.1.3 Voltage Interruption Detection
Voltage Interruption: Acuvim 3 detects voltage interruption by examining the half-cycle voltage
RMS. A voltage interruption event begins when the half-cycle voltage RMS of all channels falls
below the defined threshold and concludes when the half-cycle voltage RMS on any of themeasured channels reaches or exceeds the threshold plus the specified hysteresis voltage.
Threshold and Hysteresis: Users can customize the threshold percentage within the range of
5% to 20% and set the hysteresis percentage within the range of 1% to 10% to precisely define
the criteria for detecting voltage interruption events.
Example: When a user defines a nominal voltage of 120V and configures the voltage interruption
threshold to 5% with a hysteresis of 10%, a voltage interruption event record will initiate if all thehalf-cycle voltage RMS values drop below 6V. The voltage interruption event record will conclude
when any one of the half-cycle voltage RMS values increases to equal or surpass 18V.
In Acuvim 3, when both a voltage interruption and voltage sag meet their respective thresholds,
only the voltage interruption event will be recorded.

6.1.4 Unbalanced Voltage Detection
Unbalance Voltage: Acuvim 3 detects unbalanced voltage by monitoring the voltage unbalancefactor, which is updated at a rate of 200ms. An unbalanced voltage event starts when theunbalance factor exceeds the defined threshold and concludes when it falls below the threshold
minus the specified hysteresis.
Threshold and Hysteresis: Users can customize the threshold percentage within the range of150

V: 1.0.3 Revised: September 2024
www.accuenergy.com

Power Quality Measurements
5% to 50% and set the hysteresis percentage within the range of 1% to 10% to precisely define
the criteria for detecting unbalance voltage events.
Example: When a user configures the unbalanced voltage threshold to 5% with a hysteresis of
1%, an unbalanced voltage event record will initiate if the voltage unbalance factor exceeds 5%.
And the unbalanced voltage event record will conclude when the voltage unbalance factor is equal
to or below 4%.

6.1.5 Transient Voltage Detection
Transient Voltage: Acuvim 3 detects transient voltage by analyzing the voltage sampling values
at a rate of 32,000 samples per second (ksps). A transient voltage event is triggered when thesampling peak value of any channel exceeds the defined threshold. It’s important to note thattransient voltage events do not trigger waveform or fast log capture. Instead, they capture atransient log at 32 ksps for the 40ms duration. This mechanism allows for the precise detection
and logging of transient voltage events in the electrical system.
Threshold: Transient voltage threshold ranges from 150% to 400%.
Example: If the nominal voltage of the system is 120V, and the Acuvim 3 detects a peak voltage of360V (RMS voltage of 254V), a duration of 40ms transient voltage event will be recorded.

6.1.6 Current Sag Detection
Current Sag: Acuvim 3 detects current sag by analyzing the half-cycle current RMS. A current sag
event begins when the half-cycle current RMS of any channel falls below the specified thresholdand concludes when the half-cycle current RMS on all measured channels is equal to or exceeds
the threshold plus the specified hysteresis current.
Threshold and Hysteresis: Users can configure the threshold percentage within the range of
10% to 90% and the hysteresis percentage within the range of 1% to 10% to precisely define theconditions for detecting current sag events.
Example: When a user defines a nominal current of 5A and configures the current sag thresholdto 50% with a hysteresis of 1%, a current sag event record will commence if any one of the halfcycle current RMS values drops below 2.5A. The current sag event record will conclude when all
the half-cycle current RMS values have increased to equal or exceed 2.55A.

6.1.7 Current Swell Detection
Current Swell: Acuvim 3 detects current swell by analyzing the half-cycle current RMS. A current
swell event begins when the half-cycle current RMS of any channel exceeds the defined threshold

Threshold and Hysteresis: Users can customize the threshold percentage within the rangeof 110% to 150% and set the hysteresis percentage within the range of 1% to 10% to precisely
define the criteria for detecting current swell events.
Example: When a user defines a nominal current of 5A and configures the current swell thresholdto 150% with a hysteresis of 1%, a current swell event record will begin if any one of the half-cycle
current RMS values surpasses 7.5A. The current swell event record will end when all the half-cycle
current RMS values have dropped to equal or below 7.45A.

6.1.8 Unbalanced Current Detection
Unbalance Current: Acuvim 3 detects unbalanced current by monitoring the current unbalancefactor, which is updated at a rate of 200ms. An unbalanced current event starts when theunbalance factor exceeds the defined threshold and concludes when it falls below the threshold
minus the specified hysteresis.
Threshold and Hysteresis: Users can customize the threshold percentage within the range of
5% to 50% and set the hysteresis percentage within the range of 1% to 10% to precisely define
the criteria for detecting unbalanced current events.
Example: when a user configures the unbalanced current threshold to 5% with a hysteresis of
1%, an unbalanced current event record will initiate if the current Unbalance factor exceeds 5%.
And the unbalanced current event record will conclude when the current unbalance factor equal
to or below 4%.
