A transformer that is only designed to reduce current or voltage from a primary value to a lower value secondary that can be applied to a meter or instrument, at a proportional safer level.

A relay that operates and resets with no intentional time delay.

The initial surge of current experienced before the load resistance of impedance increases to its normal operating value.

(AMF x PS x RW)/(CU x LLF)

A quantity which is not the subject of the measurement but which influences the value of the output signal for a constant value of the measurand.
