Functions Of Relay Protection Tester

1. It can test a variety of AC and DC, current, voltage, intermediate, self-holding, signal and other single relays and a whole group of relay protection screens. It can test the pull-in voltage (current) value and release voltage (current) of various relays. ) value, the pull-in time and break-off time of various contacts (normally open, normally closed, transfer, delay) are automatically tested three times and stored, and the return coefficient of the three average values is automatically calculated and printed, which can be displayed repeatedly and print the test results.
2. It is convenient to test various parameters of the reclosing relay.
3. With the functions of frequency measurement and phase measurement, it can measure the frequency of current and voltage (displaying the time of one cycle, that is, the cycle) and the phase difference (time) between the two signals.
4. There are two independent channels, both of which are insulated from other outputs of the machine, which can easily measure live contacts and meet the online test of relays. The wiring is simple and safe.
5. It adopts a precise timing reference (10 microseconds) and a counter of up to 100 hours, so it can be used as a precision millisecond meter alone to replace the traditional stopwatch.
