What equipment depends on a utility station DC power system?

Station DC systems commonly power protective relays, circuit breaker trip and close circuits, switchgear controls, communications, annunciation, and monitoring equipment. These loads must remain available during an interruption to the normal AC supply.

How should a utility DC power system be sized?

System size is driven primarily by your DC load and required backup time. SENS can help you select the right charger, battery, and distribution configuration for your application.

Can SENS equipment communicate with a utility monitoring system?

Yes, our product-specific communication options include Modbus, DNP3, and SNMP. Available protocols depend on the selected battery charger, integrated system, or battery monitoring configuration and should be confirmed during specification.

How can battery monitoring support NERC PRC-005-6 programs?

Continuous battery monitoring can support a NERC PRC-005-6 maintenance program by collecting data, retaining records, generating alarms, and producing reports. Learn more about battery monitoring for NERC PRC-005-6

Should a utility specify an SCR or switchmode battery charger?

The right technology depends on AC input, DC output, environment, efficiency, space, service needs, and project standards. Explore SENS MicroGenius 2 and S2/S4 switchmode chargers or the EnerGenius IQ2 SCR charger.

Which battery chemistry is right for a utility application?

Start with your priorities. Choose VRLA for proven performance and lower upfront cost, SMC for long life and minimal maintenance, or LTO when fast recharge and frequent cycling are critical.
