Mô tả
The Earth Leakage Relay TM-18c / TM-8000s are micro-processor numerical based protection devices designed to recognize low-level leakage or unbalanced current due to insulation loss on conductors or faulty equipment installed in the network
They are incorporated with a real time continuous display of the earth leakage current value in true RMS ampere and allows the isolation of the faulty network or equipment if necessary.
