Prt Series Automatic Digital Microcomputer Control Relay Tester

Product Description

PRT Series Automatic Digital Microcomputer Control Relay Tester
 

PRT-I Single Phase Relay Tester
PRT-I single phase relay tester is applied to test protection replay based on voltage and current operation.

It is equipped with a fixed value output, which can be used as a voltage source.

It adopts a digital display with intuitive reading.

It has the characteristics of high precision, full function, stable, easy operation, light in weight. It's a low cost, simple operation, and reliable device for secondary circuit testing.

PRT-PC3 Three Phase Protection Relay Tester

PRT-PC3 Microcomputer relay protection tester is applied to test the relay unit in the relay protection system. At the same time, it could be considered a universal three-phase AC/DC voltage source or current source.

It is applied to test protection replay based on voltage and current operation.

The main function of the tester includes: calibration of voltage and current operation relays, secondary circuit inspection, trip value of circuit breaker test, switch on and off time measurement of circuit breaker, and so on.

It's a low-cost, simple operation, and reliable performance device for secondary circuit test.

PRT-PC6 Six Phase Protection Relay Tester

RPT-PC6 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 a 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.

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, completes 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 improve the wave quality and the accuracy of the test instrument.

Using high-fidelity linear amplifier. Both to ensure the accuracy of a low current, but also guarantee the stability of the high current.

USB directly connects with PC, without any adapter cable, easy to use.

Can be connected to a laptop computer (optional). Laptop computers and industrial machines use the same software, so there is no need to re-learn the methods of operation.

With a separate DC auxiliary voltage source, output voltage 110V(1A),220V(0.6A), provides relays or protective devices that require DC power.

The software with a self-calibrating function, which avoids to calibrate accuracy by adjusting relays after opening the case, greatly improves the stability of the accuracy.
