Electrical Power Protection and Control:
Building of MV/LV panels. Offering products and services for MV/LV transmission and distribution lines with emphasis on Smart Grid.
SF6 Circuit breakers and self-powered relays are now substituting RMUs based on switches with three fuses, but… Why?
Advantages of Self-powered Relays vs. Fuses
Low current faults: Fuses only can break high current faults. Circuit breakers with self-powered relays can detect and clear low current faults avoiding the destruction of the MV/LV transformers.
Protection Selectivity: The discrimination with fuse curves becomes difficult. It is possible to choose the right curve in self-powered relays to ensure coordination between MV and LV protection.
Inrush current: Transformer energizing produces high transient inrush current. This is a natural phenomenon, and the protection should not operate. Fuses are not able to distinguish this current, and the trip cannot be blocked. A circuit breaker with a self-powered relay allows greater flexibility to avoid the trip.
Temperature: Fuses are weak into a harsh environment, and the different temperatures can provoke two situation:
High temperature: Undesired trips.
Low temperature: The trip does not happen; instead, the fault current is high enough.
Saving Costs: Circuit-breaker with self-power reduces costs for two reasons:
Self-powered relays are maintenance-free.
There is no need to keep large stocks of fuses.
Overcurrent and Earth Fault Protection Relays with Self Powered or Dual Powered (self + auxiliary) models. The different mechanics available by model list make our SIA-C the best choice, covering all the market needs. Withdrawable model as optional.
