What Are the Differences Between Substations, Switching Stations, and Distribution Rooms?A substation is a power facility in the electric power system that transforms voltage levels, receives and distributes electrical energy, controls the direction of power flow, and adjusts voltage. It interconnects power grids of various voltage levels through its transformers. In specific applications—such as submarine power cables or long-distance transmission—some systems use high-voltage direct current (H

Power Off and Power On Sequence in the Distribution RoomPower-off sequence:When de-energizing, first disconnect the low-voltage (LV) side, then the high-voltage (HV) side. When de-energizing the LV side:First open all LV branch circuit breakers, then open the LV main breaker. Additionally, disconnect the control circuits before de-energizing the main power circuits. When de-energizing the HV side:First open the circuit breaker, then open the isolating switch (disconnector).If the HV incoming lin
