Power Quality Analyzers had a wide range of applications - most notable among them are:
Check the compliance with IEEE 1159 power standards to make sure power fed to the factories/buildings/machines are clean.
Additional algorithms available to monitor predictive health of the Motors, Heaters, Drives 24x7 continuously in the cloud and in the edge system.
Compare energy usages between different machines within a factory.
Calculate the utilization and productivity of the machines.
Measure energy usage per unit of productivity.
Estimate the actual cost of electricity by an accurate cost model of energy usage that depends on the time of the day, time of the year, etc.
Capture surge or small duration electrical event in detail using the event capture mechanism.
