EZCT Turns Ratio Measurement

The turns-ratio measurement from using this method will always have some built-in error. The amount of error depends on the size of the reactor winding and the number of turns on the CT ...

Stray voltage
Stray voltage is the occurrence of electrical potential between two objects that ideally should not have any voltage difference between them. Small voltages often exist between two grounded objects in separate locations, due to normal current flow in the power system. Large voltages can appear on the enclosures of electrical equipment due to a fault in the electrical power system, such as a failure of insulation.
