Function and Application of Microcomputer Relay Protection Tester

Function and Application of Microcomputer Relay Protection Tester
It can verify various relays (such as current, voltage, inverse time, power direction, impedance, differential, low cycle, synchronization, frequency, DC, intermediate, time, etc.) and microcomputer protection, and can simulate various complex transient, strategic management, and conversion faults for whole group testing.

Technical characteristics

Flexible combination of voltage and current output: up to 6 phase voltage and 6 phase current can be combined to achieve conventional 4 phase voltage, 3 phase current type, 6 phase voltage type, 6 phase current type, and 12 phase output mode, which is compatible with various traditional testing methods.
Single machine operation convenience: The device panel is equipped with a trackball mouse, optimized keyboard, and a large screen TFT LCD display, with built-in Chinese Windows platform operation software. Ready to use upon startup, easy and fast to operate.
Dual operation mode: In addition to single machine operation, the device can also be connected to a laptop or desktop computer for operation. The two modes have the same function and are truly a complete dual operation mode.

New type of high fidelity linear power amplifier: The output end has always adhered to the use of high fidelity and high reliability modular linear power amplifiers, rather than switch type power amplifiers, with excellent performance. It will not cause high or intermediate frequency interference on the test site, and ensures excellent smoothness and accuracy of the waveform from large current to small current.

High performance host: The output part is controlled by DSP, with fast computation speed, strong real-time digital signal processing ability, wide transmission frequency band, and control of high-resolution D/A conversion. The output waveform has high accuracy, low distortion, and good linearity. A large number of precision component materials have been used and specialized structural design has been carried out, resulting in a small volume, light weight, full functionality, and convenient portability of the device. It can work immediately upon startup, and the flow test is very convenient.
Strong software functionality: It can complete various large-scale and complex verification tasks with high automation level, conveniently test and scan various protection settings, perform fault replay, store test data in real-time, display vector maps, print reports online, etc. The 6-phase current allows for convenient testing of three-phase differential protection.
Equipped with independent dedicated DC power output: equipped with a dedicated adjustable 110V and 220V DC power output.
