Generator Differential relay
CA generator differential relay is a single phase, induction disc type with inverse timing characteristics. It is provided with one operating winding and two restraining windings without taps.
Transformer Differential relay
Designed for 2-winding transformer protection, the CA transformer differential relay has a constant percentage differential characteristic and inverse timing. It is a single-phase unit, and three relays are used for three-phase transformer protection.
Percentage Differential Relays
The CA-16 relay is a single-phase differential relay used for protection of multicircuit buses up to a total of six circuits.
The CA-26 relay provides differential protection for both 2- and 3-winding transformers. It is also suitable for combination bus-transformer applications.
