Electrical distribution box protection level 1 or 2
As for the equipment inside, there are certain differences: the first level distribution cabinet generally has isolation switches, circuit breakers, leakage protectors, etc. Two-level protection refers to the leakage protection of the main distribution box and switch box. Adequate system designs allow for the system to withstand and isolate faults while not causing additional damage and/or outages.

Function of Substation Relay Protection System
Function: Detects when current exceeds a preset value, indicating overload or short circuit. A protection relay is an intelligent device used to monitor electrical parameters such as current, voltage, frequency, and phase angle. Employ the SEL-TMU for remote data acquisition in substations with Time-Domain Link (TiDL®) technology systems.
