Residual Current Protector Tester

The residual current protector tester is an efficient and portable product specially designed and produced for the detection of residual current operated protectors.

The operating current, operating time, and limit non-operating time of the residual current-operated protector can be tested online and offline; the voltage of the tested circuit can be displayed in real time. It has the characteristics of simple operation, automatic detection, data retention, etc., which is especially suitable for the use and promotion of electricity security inspection departments and power supply stations at all levels.

★Thirteen gears from 10mA to 1000mA are provided to adapt to different types of residual current operated protectors

★Online and offline measurement of residual current operating characteristics of residual current operated protectors

★The limit non-driving time of the delayed residual current relay can be measured, and seven gears such as 60ms, 100ms, 200ms, 300ms, 400ms, 500ms, 1000ms can be selected.

★The remaining non-operation current test can be performed, and the time files of 300ms, 400ms, and 500ms can be selected.

★With digital display, counting retention, and automatic detection functions

★The residual current protector tester has the function of real-time display of the line voltage of the line under test

★Two minutes of no operation will automatically power down to increase battery life

★The residual current protector tester can directly measure the residual current operated protector with zero sequence current transformer

The residual current protector tester has two test leads. One end of the test line is connected to the socket of the corresponding color of the tester, the other end is a black alligator clip test line that clamps the neutral or ground line, and the test lead of the red test lead touches any phase of the protector. Wire (to ensure that the test current loop passes through the induction coil inside the residual current action protector).

Special reminder: When testing the residual current operated protector with zero sequence current transformer, the red test pen touches the relay outlet phase terminal controlled by the residual current operated protector, and the black test pen is connected to the nearest grounding wire for measurement.
