Sensitive 5A Earth Fault Protection Relay for Earth Leakage Protection

 

 

 A relay used in the power system to detect neutral or ground faults measure the vector difference of the three phase power, or measure the neutral current directly. 

 

Description:

 

KRIPALRelay is a micro-mrocessor based electronic protection device  designed  to recognize current leakage to ensure the protection  of electrical installations  and persons  against  direct  and indirect contacts.

 

cost-effective earth fault relays comprehensively detect and activate trip protection to medium and low voltage applications. The series of earth fault relays are microprocessor-based numerical relays and are housed in resilient mounted casing. The high end model, IDMT characteristic curves which provide multiple matching protection characteristics curve for different load types.
