Apply two three-phase winding inputs and an optional single-phase transformer comprehensive protection to limit ground fault input and three-phase voltage input. The benefits include automation and flexibility, single or dual, copper or fiber optic Ethernet communication ports, asset management data, and easy to retrofit electromechanical relays.

Overview:

Distinctive applications

Global Protection Pro provides simple and economical protection for transformers, circuit breakers, motors, capacitor banks, feeders, with two independent three-phase overcurrent relays and other equipment in a compact package. The torch relay provides numerous protection schemes, which are set and enabled by users.

The dual relays on both sides of Versatility Set correspond to different applications. For example, a feeder application on one side and an application on the other side for circuit breaker faults.

Complete branch line protection - Install two SEL-501/501-2 dual universal overload/dual overcurrent relay switches to protect two separate feeders in a two roll crusher. This provides primary protection and backup for each feeder line.

Transformer Protection Connect dual relay, CTs on one side of the transformer for transformer overload and overcurrent protection. The relay on the other side is connected to the neutral CT in the Huaiyi delta wye transformer for sensitive internal ground fault protection and backup external fault protection.

SEL protection relay in the United States

Selected power system protection by establishing * microprocessor-based protection relays. Today, we have selected high-speed protection relays for safe and reliable fault detection; Accurate fault location; Integrated automation and control functions. Select the market with the highest mean time between failures (MTBF) for relays (in 500 years).
