This can be done manually via the relay front panel controls, or using a portable PC and suitable software. Whichever, method is used, a check by a second person that the correct settings have been used is desirable, and the settings recorded.
Programmable scheme logic that is required is also entered at this stage. The ammeter connected to the secondary of the current transformer should be a robust moving coil, permanent magnet, centre-zero type.
A low voltage battery is used, via a single-pole push-button switch, to energise the primary winding.

This can be done by energising the secondary winding from the local mains supply through a variable auto-transformer while the primary circuit remains open. See Figure 2. The characteristic is measured at suitable intervals of applied voltage, until the magnetising current is seen to rise very rapidly for a small increase in voltage. This indicates the approximate knee-point or saturation flux level of the current transformer.
The magnetising current should then be recorded at similar voltage intervals as it is reduced to zero. The short-time current rating must be in excess of the CT secondary current rating, to allow for measurement of the saturation current. This will be in excess of the CT secondary current rating.
As the magnetising current will not be sinusoidal, a moving iron or dynamometer type ammeter should be used. It is often found that current transformers with secondary ratings of 1A or less have a knee-point voltage higher than the local mains supply.

The Relay Testing Handbook is a nine-part series that covers virtually every aspect of relay testing. It takes a relatively small amount of power to turn on a relay but the relay can control something that draws much more power. Gregg Press Subject: These are operated to open or close the load contacts in response to one or more electrical quantities like voltage and current.
The reason for the discrepancy will not be a change in the relay characteristic but a change in the test conditions, for exam-ple, the relay's proximity to a steel cabinet.
