1、 Product Introduction:
MHWGB9500-IThe wireless high-voltage ratio tester breaks through the traditional structure and is carefully designed and manufactured for measuring the current, ratio, and leakage current of high and low voltage primary and secondary circuits. It adopts the latest CT technology and mask digital integration technology, and consists of a dedicated high-voltage detector, low-voltage current clamp, host, high-voltage insulation rod, monitoring software, etc. Its wireless transmission test data can penetrate obstacles in multi story buildings, with a linear transmission distance of up to 30 meters. If insulation rods are not used, they can also be used as high-precision low-voltage clamp ammeters and leakage ammeters, which can accurately measure currents or leakage currents ranging from 0.01mA to 1000A.
2、 Product features:
1. The current clamp is made of special alloy and adopts the latest CT technology and magnetic shielding technology, which is almost unaffected by external magnetic fields, ensuring high-precision, high stability, and high reliability for continuous monitoring throughout the year.
2. The host has a luxurious blue screen LCD display, which is clear at a glance, and also has a large storage space that can store 3000 sets of data.
3. The monitoring software has online real-time monitoring and historical query functions, dynamic display, waveform indication, transformation ratio, frequency indication, maximum, minimum, and average value indication, alarm value setting and alarm indication functions, historical data reading, viewing, saving, analysis, processing, sorting, curve fitting, reporting, printing and other functions.
4. The high-voltage detector is connected to the insulation rod and can be used for measuring the current of high-voltage lines below 60KV, testing the current size and transformation ratio on both sides of transformers, online current monitoring. Its dedicated high-voltage current clamp can easily clamp or withdraw the tested wire by pressing or pulling out the insulation rod, saving time and speed. It is widely used in substations, power plants, industrial and mining enterprises, testing stations, electrical maintenance departments for current detection, power inspection, field electrical operations, etc. The insulating rod is lightweight, with characteristics such as moisture resistance, high temperature resistance, impact resistance, bending resistance, high insulation, and stretchability.
