The relay protection tester under HV Hipot Electric Co., Ltd. power can help many power workers conduct various power tests more conveniently.
Microcomputer relay protection tester is a type of power testing equipment that power operators will come into contact with during the operation process. This equipment is also an important testing device 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 testing relays. So, how large is the application scale of microcomputer relay maintenance tester in the power system? This article is for you.
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, inverse time limit, power direction, synchronization, frequency, reclosing, etc.
2. Suitable for complete transmission systems. It can not only simulate various transient and permanent switch faults, but also superimpose transient DC components on the fundamental wave.
3. Used for AC and AC/DC phase separated output at different frequencies.
4. Automatic testing of differential equalization and harmonic suppression characteristics for microcomputer main transformer maintenance.
5. Suitable for maintenance of automatic testing group intervals, zero sequence, and overcurrent.
6. Used to detect motor demagnetization, unsynchronization, reverse excitation, reverse power, and synchronization maintenance.
