ETCR9550B Wireless High and Low Voltage Turn Ratio Tester break through the traditional structure, special designed and manufactured for online measurement of current transducer, transformer primary current and secondary current, transformation ratio, phase and polarity judgment below 35kV in operation. The instrument is composed of primary current clamp (high voltage detector), secondary current clamp, host machine, high voltage insulation rod, monitoring software, communication cable, etc. The instrument is equipped with two types of primary current clamps: high voltage current clamp and flexible current clamp, which can cope with various testing sites. Among the high-voltage current clamp use wireless transmit the test data, which transmission distance of 100 meters.
The current clamp is made of high performance permalloy with magnetic shielding technology, which is almost free from the influence of the external magnetic field, ensuring the long time uninterrupted monitoring of high accuracy, high stability and high reliability.
The host LCD display clear and obvious, with large storage space, can store 3000 groups of data.
The high voltage detector connect with 5pcs insulation rods, used for high voltage line current measurement which the wire with insulation skin below 60KV or the bare wire below 35KV, high voltage current clamp have unique automatic plug and pull structure, by pressing or pulling out the insulation rod can be easy to clamp or withdraw the tested line, saving time and more effective. It is widely used in substations, power plants, industrial and mining enterprises, inspection stations, electrical maintenance departments for current detection and electrical field operations. The insulation rod is handiness, and has the characteristics of moisture-proof, high temperature resistance, impact resistance, bending resistance, high insulation, scalable and so on. Insulation level 110KV.
ETCR9550B Wireless High and Low Voltage Turn Ratio Tester,also have the functions of high and low voltage clamp meter, high altitude current tester and so on
