The output part of the microcomputer relay protection tester adopts DSP control, with fast operation speed, strong real-time digital signal processing capability, wide transmission bandwidth, and high-resolution D/A conversion control. The output waveform has high accuracy, low distortion, and good linearity. It adopts advanced technology and precision component materials, and has undergone professional structural design, so the device is small in size, light in weight, full in function, and easy to carry. It can work immediately after power-on, and mobile testing is very convenient. There are many application ranges, and today the editor has compiled them as follows:
1. Used to test all individual components in the secondary dispatching of various relays. Various relays include: voltage, current, differential, time, negative sequence, balance, distance, inverse time, power direction, synchronization, frequency, reclosing, and other relays.
2. Used in the entire gearbox. It can not only simulate various simple or complex transient and permanent transition faults, but also superimpose transient DC components on the fundamental wave.
3. Suitable for split-phase output AC at different frequencies, as well as AC and DC.
4. Used for automatic testing of the differential ratio and harmonic suppression characteristics of microcomputer main transformer protection.
5. Used for automatic testing of the entire set of distance, zero-sequence, and overcurrent protection.
6. Used for testing various protections such as loss of excitation and synchronization, flyback, reverse power, and motor synchronization.
The above are the application ranges of the microcomputer relay protection tester, which makes this instrument play a very important role in power line protection
