Technical FAQs 4

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.

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 do switchgear and substation power systems work together?

Switchgear and substation power systems work together to deliver electric power and reduce potential downstream faults ensuring safe electrical power. With the power utility landscape changing in terms of both architecture and methods of generation, the need for reliable energy storage solutions is growing.

Why do substations need reliable energy storage solutions?

With the power utility landscape changing in terms of both architecture and methods of generation, the need for reliable energy storage solutions is growing. Substations are evolving and adapting to support new and varied generation sources including renewables.
