• The mainframe LCD display is clear at a glance, and it also has a large storage space, capable of storing 3,000 sets of data.
• The current clamp is made of high-performance PoMo alloy and magnetic shielding technology, which is virtually unaffected by the external magnetic field, ensuring high precision, high stability and high reliability for year-round uninterrupted monitoring.
• Wireless HV Current Transformation Ratio Tester breaks through the traditional structure, specializing in on-line measurement of high-voltage current transformer in service under 60KV, primary and secondary current of transformers, transformation ratio, and leakage current(it also with phase, polar, ratio difference, angle difference Indication).
• It consists of high voltage detector, low-voltage secondary current clamp, main engine, high-voltage insulation rods. The wireless transmission signal is able to penetrate obstacles, such as walls of buildings. The signal’s linear transmission distance is about 30m. The HV high accuracy clamp ammeter can be used to measure the current and leakage current varying from 0.01mA to 1000A.
• Wireless HV Current Transformation Ratio Tester is called Wireless Transformation Ratio Tester for high voltage; meanwhile it can function as high/low-voltage clip-on ammeter, for high-altitude current tester, high-altitude leakage current tester, clip-on leakage current meter with high accuracy and other products.
