Brief introduction
HTCT-201 breaks the traditional structure, specializing in on-line measurement of high-voltage current transformer in service under 60KV, primary and secondary current, ratio, and leakage current of transformers. It consists of high voltage detector, low-voltage current clamp, main tester, high-voltage insulation rods. The wireless transmission signal is able to penetrate obstacles, such as walls of buildings, does not affect the readings. Without the use of insulating rod, it can also be used as high-precision low-voltage clamp meter or leakage ammeter.
Current clamp: In order to make sure of the high accuracy, stability and reliability during perennial monitoring, special alloy is selected, latest CT technology and magnetic shield technology  are adopted,which make sure almost resistance to external magnetic field.
