How to protect the leakage protector leakage protection?

Answer:

Also known as leakage relays are often used to maintain an important place for electricity. RCD principle for the use of zero sequence current
can be divided into high sensitivity. Sensitivity and low sensitivity. Its working principle is my + I = nine = 0
Capture leakage, electric shock and other ground fault current. Trip and strokes according to its breaking reaction time cut off the power
Third, do not overload short circuit protection. Nor is it a direct frequency circuit, leakage alarm only the role of RCD.
