MEWOI1550C Wireless High/Low Voltage CT/(Transformer) ratio tester/phase angle tester

INTRODUCTION

MEWOI1550C Wireless H/L Voltage Transformation Ratio Tester special designed and manufactured for online measurement of current transducer, transformer primary current and secondary current, transformation ratio, phase angle,phase and polarity judgment below 35kV in operation. 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 primary current clamp adopt wireless to transmit which transmission distance of 100 meters.

The current clamp is made of high performance perm alloy 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, with large storage space, can store 3000 groups of data. the high voltage detector connect with 5pcs insulation rod, which can use for high voltage line current measurement of  the wire with insulation skin below 60KV or  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 wire, saving time and more effective. It is widely used in substations, power plants, and 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.

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, accessing, saving, printing and other functions. MEWOI1550C Wireless H/L Voltage Transformation Ratio Tester, at the same time: H/L voltage clamp current meter, high altitude current telemeter and other products functions.
