General Information:
Protection systems play a key role for the safe and reliable operation of today’selectricity power systems. Properly working protection devices help to maintainthe safety of the system and to safeguard assets from damage. EPRP-304 Relay Protection Tester is the essential test tool for relay protection technicians.
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 tester.
Classic Windows XP operating interface, friendly man-machine interface, easy and fast to operate. High-performance embedded industrial control computer and8.4 inch resolution of 800 × 600 TFT true color display which provides richvisual information, includes the current working condition and all kinds of help information.
The software with self-calibrating function, which avoid to calibrate accuracy by adjusting relays after open the case, greatly improve the stability of the accuracy.
Features:
Meets all the requirement of field tests. This tester with standard4phase voltage, 3phase current output, voltage 125V/phase, current30A/phase, 3phases in parallel can up to 120A.
Digital Signal Processor Microcomputer. Not only test the traditionalrelays and protectors, but also test the modern microcomputer relays, specialfor transformer differential protection and transfer equipment.
All technical indicators fully meet the standard DL/T624-1997: Technicalcondition of the relay computer test device.
Classic Windows XP operating interface, friendly man-machine interface,easy and fast to operate; High-performance embedded industrial control computerand 8.4 inch resolution of 800 × 600 TFT true color display which provides richvisual information, includes the current working condition and all kinds ofhelp information.
The Windows XP system comes with the restore function; avoid system crashes causeddue to illegal shutdown, or malfunction, etc.
Equipped with ultra-thin industrial keyboard and optical mouse, complete avariety of operations using keyboard or mouse the same as 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 tester.
Using high-fidelity linear amplifier. Both to ensure the accuracy of a lowcurrent, but also guarantee the stability of the high current.
USB directly connect with PC, without any adapter cable, easy to use.
Can be connected to a laptop computer (optional). Laptop computers andindustrial machines use the same software, no need to re-learn the methods ofoperation.
With a separate DC auxiliary voltage source, output voltage110V(1A),220V(0.6A), provides relays or protective devices which require DCpower.
The software with self-calibrating function, which avoid to calibrateaccuracy by adjusting relays after open the case, greatly improve the stabilityof the accuracy.
