I. DC high voltage tester Introduction
Our company is a high-tech jo int-stock enterprise established by masters and doctors, after studying in Australia or USA, and bachelors, after studying in Tsinghua University, with high voltage, power system, automatic control and computer specialities background. Our products are widely used in great electric power companied of Australia, USA, Canada and other countries.
ZGF 2000 Series portable high voltage direct current generators are high reliability, high quality, really portable testing equipment developed by ADELONG Co. of Australia, HYPER EQUIP Co. of USA and our company, adopting the most advanced technologies combined with Chinese situations, facing home, used for DC high voltage test of zinc oxide arrester, power cable, generator, transformer, switch and other equipment in power departments, industrial and mining enterprise power departments, and power plants. They are perfect new generation products replacing old ones in 21st century.
1. DC high voltage tester Characteristics
① DC high voltage tester Smaller size, lighter weight, more beautiful appearance, more reliable performances, easier operation, complete functions. The product is a perfect new generation product replacing old one in 21st century.
② DC high voltage tester The product is manufactured with the most advanced technologies and processing method. Pulse train is modulated by logic array, high-power IGBT devices are adopted, phase fuzzy controlled, so more reliable output and less ripple can be obtained, frequency is up to 100kHz.
③ DC high voltage tester Maintenance free design. Main components are imported from Germany, USA and Japan, durable and wear well, can continuously short circuit discharge directly to ground.
④ DC high voltage tester High precision, accurate measurement, output voltage is regulated by single multi-turn potentiometer, smooth voltage rise, high precision adjustment, and with coarse and fine adjustment. The instrument possesses electric leakage measurement at high and low voltage terminals. At high voltage terminal there is spherical shield digital meter display, capable of bearing discharge impact. Excellent immunity, applicable to the site.
⑤ DC high voltage tester DC high voltage tester Voltmeter on the control box directly shows voltage value on load sample, during operation, no exterior voltage divider or current-limiting resistor is necessary, simple wiring, easy operation.
⑥ DC high voltage tester DC high voltage tester Negative polarity output, zero start, continuous adjustable, with overvoltage, overcurrent, zero, ground protection, wiring broken protection, powerful automatic protection function, safe operation, all technical indexes are better than similar products.
⑦ DC high voltage tester 75% function facilitates zinc oxide arrester measurement. There is 75% voltage switch function on the control box of this instrument, when current goes up to 1000uA, turn on the 75% button, now voltmeter and ammeter will show 75% data. At the end, immediately turn voltage rise knob to zero, and fine adjust knob to zero. Turn the 75% button to normal position, then continue other test.DC high voltage tester
