Numerical Transformer Differential Relay By Jvs Electronics Pvt. Ltd.

Numerical Transformer Differential Relay provides differential protection for power transformer. Relay measures the line current of each phase from each windings of transformer. Relay calculate differential current (Id) and restraining current (Ir) per phase. The differential characteristics define the operating and the restraining regions.

Features of Numerical Transformer Differential Relay:
* Based current differential protection.
* Fast differential Hi-set.
* Dual slope characteristics.
* Inbuilt CT ratio correction factor.
* Adjustable 2nd harmonic restraint.
* Adjustable 5th harmonic blocking.
* Inbuilt vector group compensation.
* Two groups of settings.
* History of 5 latest faults.
