BJS-150A Relay Protection Tester

Detailed information:

BJS-150A Relay Protection TesterMainly used for performance testing of protective relays such as voltage, current, time, intermediate, and power. This test has the characteristics of complete functionality, small size, light weight, sturdy use, and easy portability. The outstanding feature of this tester is that it adopts a single chip, high-precision digital ammeter that directly displays the output current within the range of 0-150A and the electronic millisecond meter, and displays AC voltage and DC voltage, making on-site operation more convenient and intuitive.

Communication calibration:

BJS-150A Relay Protection TesterClick on "Output AC", and the device will output a voltage of 50V per phase and a current of 5A per phase according to the set values. Use a high-precision meter to measure the actual output values of each phase voltage and current, fill in all the measured values in the "Measurement Value" column, then click "Stop Output" to stop the device from outputting voltage and current, and then click "AC Calibration". Enter the password to complete the process

DC offset calibration:

In the absence of output from the device, the power switch of the amplifier must be turned on. Use a DC voltmeter and DC ammeter to measure the DC components of each phase voltage and current channel. Fill in the corresponding "DC offset" column (unit: millivolts, milliamps) with the measured DC components of each phase, then click "offset calibration" and enter the password.
