Self or Dual-Powered Supply for Protection Relay: MCCBs & ACBs Ref Design
Description
This power supply solution for Protection Relays & MCCBs handles both the current input from a Current Transformer (CT) or input from an Auxillary (Aux) source. The self-powered" capability comes from being able to harness the power available in the grid through the CT. The flexibility of this solution's "dual-power" input comes from the ability to also handle the Aux input - which is often a battery source."
Features
- Higher shunt regulation voltage reduces power loss and improves efficiency Provides option for customer to use a CT with lower VA to reduce size of the product/transformer Excellent load transient performance and very sharp turn-on characteristic Simple and cost-effective electrical surge-protection circuitry for a wide range of applications
Applications
- Fault indicator (FI)
- Grid asset monitoring
- Substation automation
- Circuit breaker (ACB
- MCCB
- VCB)
Product Categories
- Power management
