Protection Relay Testers for Choice:
PRT-PC6 Computer Control Six-Phase Protection Relay Tester
Product Description
RPT-PC6 Six Phase Protection Relay Tester with standard 6 phase voltage and 6 phase current output, voltage 125V/phase, current 30A/phase, 6 phases in parallel can up to 180A.
With digital Signal Processor Microcomputer, it can not only test the traditional relays and protectors but also can test the modern microcomputer relays, especially for transformer differential protection and transfer equipment testing.
Features
Classic Windows XP operating interface, 8.4-inch resolution of 800*600 TFT true color display.
Equipped with an ultra-thin industrial keyboard and optical mouse, complete a variety of operations using the keyboard or mouse the same as an ordinary PC.
The main control board is DSP + FPGA architecture, 16-bit DAC output, generates high-density sine wave 2000 points each circle to fundamental wave, which greatly improves the wave quality and the accuracy of the test instrument.
Using high-fidelity linear amplifier. Both to ensure the accuracy of a low current and also to guarantee the stability of a high current.
USB directly connects to the PC, without any adapter cable, easy to use.
It can be connected to a laptop computer (optional). Laptop computers and industrial machines use the same software, there is no need to re-learn the methods of operation.
With a separate DC auxiliary voltage source, output voltage 110V(1A), and 220V(0.6A), provide relays or protective devices that require DC power.
The software with a self-calibrating function, which avoids calibrating accuracy by adjusting relays after opening the case, greatly improves the stability of the accuracy.
