  ETCR9500C-030 Three-channel Wireless HV Transformation Ratio Tester is our company new core technology products which has been committed to power meter testing technology research for a long time. It is specially designed and manufactured for online measuring and verifying the H/L voltage current transducer, primary and secondary current magnitude of transformer, transformation ratio, ratio error phase, polarity, phase sequence in the operate distribution system below 35kV. The instrument consists of special primary high voltage current clamps, 3-channel secondary low voltage current clamps, host machine, high voltage insulation rod, monitoring software, communication cable etc. This instrument adopts 3pcs secondary low voltage current clamps to test the low voltage circuit simultaneously, which can directly determine the corresponding phase relationship between the high voltage end and the low voltage end, do not require totesting many times.

    ETCR9500C-030 Three-channel Wireless HV Transformation Ratio Tester widely used in substations, power plants, electric power inspection departments, industrial and mining enterprises, inspection stations, electrical maintenance departments for current detection, anti-theft and electrical field operations. The primary high voltage current clamp break through the traditional structure and have the function of automatic opening and closing. By pressing or pulling out the insulation rod can convient to clamp or withdraw the tested wire easily,  safety and save time. The insulation rod is handiness, and has the characteristics of moisture-proof, high temperature resistance, impact resistance, high insulation. The high voltage current clamp and the host machine adopt wireless transmission, can penetrate the barrier of the partition wall, and the straight line transmission distance is 100 meters. Secondary current clamps 008 current clamps are suitable for the line test of flat cable dense. The current clamp are made of permalloy and adopt CT magnetic shielding technology to ensure the  high accuracy, high reliability and high stability of continuous monitoring in a long time.
