The microcomputer relay protection tester is a type of power testing equipment that power operators will come into contact with during operation. This device is also an important testing equipment widely used in power system line maintenance. Due to the precise and disorderly maintenance function of relays on power lines, microcomputer relay maintenance testers generally have the characteristics of high performance, high precision, and high technical requirements as test relays. So, what is the scale of application of microcomputer relay maintenance testers in power systems?
1. Used to test all individual components in the secondary scheduling of various relays. Various relays include voltage, current, differential, time, negative sequence, balance, interval, reverse time, power direction, synchronization, frequency, reclosing, etc.
2. Suitable for complete transmission equipment. It can not only simulate various transient and permanent switch faults, but also superimpose transient DC components on the fundamental wave.
3. Used for split phase output of AC and AC/DC flow at different frequencies.
4. Automatic testing of differential equalization and harmonic suppression characteristics of main transformers for microcomputer maintenance.
5. Suitable for maintenance of automatic testing group intervals, zero sequence, and overcurrent.
6. Used to detect motor loss of excitation and synchronization, reverse excitation, reverse power, and synchronization maintenance.
