Description
The product is composed of primary current clamp (high voltage detector), secondary current clamp, host machine, high voltage insulation rod, monitoring software, communication cable, etc. The test data of the primary current clamp adopts wireless to transmit whose transmission distance of 100 meters.
The clamp meter is made of high-performance permalloy with magnetic shielding technology, which is almost free from the influence of the external magnetic field, ensuring long-time uninterrupted monitoring of high accuracy, high stability and high reliability. The clear host LCD screen, with large storage space, can store 3000 groups of data. The high-voltage detector is connected with a 5-piece insulation rod, which can be used to measure the current of the high-voltage line of insulation-sheathed cable below 60KV or bare wire below 35KV, the high-voltage current clamp has a unique automatic plug and pull structure, Pressing or pulling The insulation rod can be easy to hold or remove the tested wire, which saves time and is more effective. It is widely used in substations, power plants, industrial and mining enterprises, inspection stations, electrical maintenance departments for current sensing and electric field operations. The insulation rod is practical and has the characteristics of moisture resistance, high temperature resistance, impact resistance, bending resistance, high insulation, scalable, etc. 110KV insulation level.
The monitoring software has the functions of online real-time monitoring and historical query, dynamic display, maximum, minimum and average indication, alarm value setting and alarm indication, and with historical data reading, access, saving, printing and other functions. Wireless H/L voltage transformation ratio tester ETCR9550B, at the same time: H/L voltage clamp current meter, high-altitude current rangefinder and other product functions.
Fuction H/L voltage current transducer, transformer primary and secondary circuit current, transform ratio, polarity and phase adjustment
