What is a base station power cabinet?

The base station power cabinet is a key equipment ensuring continuous power supply to base station devices, with LLVD (Load Low Voltage Disconnect) and BLVD (Battery Low Voltage Disconnect) being two important protection mechanisms in the power cabinet.

Why do substations need a DC power supply?

This output can be utilized while making a battery discharge test during substation commissioning or regular maintenance and testing. Since the DC system supplying specially relay protection, control, and interlocking circuits is of paramount importance to the substation’s reliable and safe operation, the energy supply has to be always available.

How many DC systems can a power substation have?

A power substation can have one or several DC systems. Factors affecting the number of systems are the need for more than one voltage level and the need for duplicating systems. Today, normal DC auxiliary supply systems in power substations are operating either on the 110 V or 220 V level, though lower levels exist.
