Overview

The current clamp of the CT comprehensive tester is made of high-performance Permalloy and equipped with magnetic shielding technology, which is almost unaffected by external magnetic fields, ensuring high precision, stability, and reliability for continuous monitoring throughout the year. The host LCD display is clear at a glance, and it also has a large storage space that can store 3000 sets of data

Product Details

UHV-201CT comprehensive testerBreaking through traditional structures, it is carefully designed and manufactured for online measurement of primary and secondary currents, transformation ratios, phase and polarity judgments of current transformers and transformers below 35kV. The product consists of a primary current clamp (high-voltage detector), a secondary current clamp, a host, a high-voltage insulation rod, monitoring software, communication lines, etc. The primary current clamp uses wireless transmission of test data with a transmission distance of 100 meters.

The main current clamp is made of high-performance Permalloy and magnetic shielding technology, which is almost unaffected by external magnetic fields, ensuring high precision, stability, and reliability for continuous monitoring throughout the year.

The host LCD display is clear at a glance, and it also has a large storage space that can store 3000 sets of data.

The high voltage detector is connected to 5 insulated poles and can be used for current measurement of high and low voltage lines with insulated outer skin below 60kV or bare wires below 35kV. The high voltage current clamp has an automatic insertion and extraction structure, which can easily clamp or withdraw the measured wire by pressing or pulling out the insulated pole, saving time and speed. It is widely used in substations, power plants, power inspection departments, industrial and mining enterprises, as well as testing stations and electrical maintenance departments for current detection, anti electricity theft, and field electrical operations. The insulating rod is lightweight, with characteristics of moisture resistance, high temperature resistance, impact resistance, bending resistance, and high insulation, with an insulation level of 110kV.

The monitoring software has online real-time monitoring and historical query functions, dynamic display, with minimum and average value indications, alarm value setting and alarm indication functions, and historical data reading, viewing, saving, printing and other functions.
