South Dakota Administrative Rules › Title 20 - PUBLIC SAFETY › Article 20:10 - PUBLIC UTILITIES COMMISSION › Chapter 20:10:39 - Stray electrical current and voltage remediation rules › Section 20:10:39:22 - Use of remote reference grounding electrodes

Current through Register Vol. 51, page 10, July 15, 2024
Remote reference electrodes are established by installing
				  ground rods. In preparation for testing, each ground rod must be installed and
				  penetrate soil to a depth of approximately 30 inches. When practicable, each
				  remote reference electrode is installed at least 25 feet away from the nearest
				  underground conductive electrical equipment of any type or at a distance equal
				  to three to four times the buried depth of any metallic structure connected to
				  the service entrance neutral. When practicable, each remote reference electrode
				  must be located no closer than 25 feet from the centerline of a primary
				  electrical conductor right-of-way and no closer than 100 feet from the edge of
				  a transmission line right-of-way.
Each remote reference electrode must be checked for
				  remoteness prior to its use for tests or measurements, and, if found to be
				  insufficiently remote, a new location for that remote reference electrode must
				  be found and retested for remoteness. Remoteness of the remote reference
				  electrode is determined by measuring the voltage from the transformer grounding
				  electrode to the remote reference electrode. The ground electrode resistance
				  and current at the transformer are also measured. Remoteness is considered
				  adequate if the measured voltage between the transformer grounding electrode
				  and the remote reference electrode is within 20 percent of the voltage
				  calculated by multiplying the transformer grounding electrode current by the
				  transformer grounding electrode resistance. If the transformer grounding
				  electrode is within 25 feet of other primary or secondary grounding electrodes,
				  this remoteness test is conducted at the first primary system grounding
				  electrode upstream of the transformer that is greater than 25 feet from other
				  primary or secondary system grounding electrodes.

Current through Register Vol. 51, page 10, July 15, 2024
The K factor is a calculated ratio of cow contact
				  voltage/secondary neutral to reference voltage. The K factor should be less
				  than one because cow contact voltage should be less than secondary neutral to
				  reference voltage. If the K factor is greater than one, then there is
				  contribution to cow contact voltage from sources other than secondary neutral
				  to reference voltage.

Current through Register Vol. 51, page 10, July 15, 2024
During the signature test, individual pieces of major
				  current drawing equipment are started and stopped. The effects of starting,
				  operating, and stopping each piece of equipment are measured and recorded for a
				  period of operation of at least 15 seconds. The person conducting the test
				  identifies and records the equipment being tested and records the specific
				  times that the equipment was started and stopped. A digitizing data recorder
				  with averaging capability is used to measure and record the required electrical
				  data. These measurements are taken at the same locations at the dairy where
				  measurements were taken for the purpose of the load box test and 48 hour test.
				  The following measurements are taken:
(1) Voltage from primary neutral at the
				transformer to remote reference electrode;
(2) Voltage from secondary neutral in the
				service panel serving the area of the cow contact to remote reference
				electrode;
(3) Voltage from primary
				neutral at the transformer to secondary neutral at the service panel serving
				the area of cow contact; and
(4)
				Cow contact voltage or cow contact current at the preselected point.

The person analyzing the data collected examines the data

				  contact current and primary neutral to reference voltage at time of maximum cow
				  contact voltage or current. These values are recorded as Vcc48 hr, Icc48 hr, or
				  Vp48 hr. The three data sets created from the values are:
(1) The primary to reference ground voltage
				and the cow contact voltage or cow contact current measured during the load box
				test with the farm power "off" and the load box "off" are recorded as Vp OFF
				and either Vcc OFF or Ice OFF;
(2)
				The primary to reference ground voltage and the cow contact voltage or cow
				contact current measured with the load box set at one-half load are recorded as
				Vp HALF LOAD and either Vcc HALF LOAD or Ice HALF LOAD; and
(3) The primary to reference ground voltage
				and the cow contact voltage or current measured with the load box at maximum
				are recorded as Vp FULL LOAD and either Vcc FULL LOAD or Ice FULL

Current through Register Vol. 51, page 10, July 15, 2024
The utility contribution to cow contact voltage or cow
				  contact current for dairies with three-phase balanced load service is
				  determined by directly using the results of the load box test results for step
				  1 and step 2 as specified in §
									20:10:39:50.
The cow contact voltage measured during step 1 of the load
				  box with the load box "off" and the dairy "on" will be the total cow contact
				  voltage. The cow contact voltage measured during step 2 of the load box test
				  with the load box "off" and the dairy "off" is the contribution to cow contact
				  voltage from the utility or Vcc utility. The contribution to cow contact
				  voltage by the dairy is the difference between cow contact voltage and cow
				  contact voltage from the utility. The formula is: Vcc dairy = Vcc - Vcc
				  utility.
