Voltage testing device EPRP-304

currentcomputer-controlledprotection relay

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.
