Ground fault Residual current is also called an electric shock protector when it is used. It is an important protective electrical device that is effective in preventing low-voltage and leakage accidents when it is used. Residual current action protectors have been widely used in urban and rural users, so that users can effectively avoid the electric shock damage that may be caused by accidental contact with live equipment. In rural areas, people simply call the residual current action protector "life-saving device". This article focuses on the operation and maintenance management of the residual current action protector.
After the ground fault residual current is put into operation, its use unit should effectively establish its operation record and corresponding management system. The power management personnel should at least perform the power-on trip test for the residual current action protector every month, that is, press the test button to Check if the residual current action protector is reliable. When a residual current action protector is actuated by lightning strikes or other reasons, it shall be checked and a trip test shall be performed. During the peak season of rural electricity consumption, the number of test hops should be increased. The deactivated residual current action protector should be tripped once before use.
Ground fault residual current In order to fully grasp the operating condition of the current action protector during operation, the residual current action protector should be sampled and tested regularly during use.www.ctsensorducer.com
