ETCR9500B-Wireless High Voltage Current Transformation Ratio TesterETCR9500B-Wireless High Voltage Current Transformation Ratio Tester
Function:
Measurementof primary and secondary circuit current, transformation ratio, polarity and phase of current transformers and potential transformers below 35kV.
Introduction:
ETCR9500B Wireless High Voltage Current Transformation Ratio Tester breaks traditional structure, specially designed for high and low voltage first and secondary loop current, variable ratio, phase, polar, ratio difference, angle difference and current leakage test; apply the latest CT technology and mask digital integration technology, composed of special high-voltage clamp, low voltage clamp, host, high voltage insulation rod and monitoring software, etc; its wireless transmission test data can penetrate multiple building obstacles with a straight-line distance of 30 meters. Monitoring software has online real-time monitoring and historical query function, with dynamic display, wave direction, variable ratio, frequencyindication, with maximum, minimum, mean value indication; alarm setting and alarm indication functions, functions of historical data reading, access, saving, analysis, processing, sorting, fitting curve, report and printing. High-voltage detector connected rod can be used in the measurement of high voltage line current, currents on both sides of transformer, variable ratio test, online current monitoring below 60KV; The special clamp ammeter can facilitate clamp to exit the tested lead by pressing or pulling back insulation bar, which is time efficient and convenient; widely used in power plant, substation, industrial and mining enterprise, inspection station, electrician maintenance department for current sensing, power audit and field working
