1. Basic information

Product Model: SR-750-P5-G5-S5-HI-A20-R-T

Manufacturer: GE Multilin

Product series: 750 series feeder management relays

Second, functional characteristics

Programmable set point menu navigation: This relay provides programmable set point menu navigation, allowing users to navigate the field menu via keyboard and directly access metering, status, maintenance, trip counter, arc current and more Settings.

Security: Hardware and password security features to lock out unauthorized changes and ensure device security and stability.

Versatility: Can be used to define protection elements, collect system data, define output contact power-on, define circuit breaker closure, and define circuit breaker monitoring. At the same time, it can also perform monitoring functions such as delay, circuit breaker timing, alarm and trip values, and minimum and maximum values.

Extensive input and output options: Multiple input and output options are supported, including 5 A phase current inputs, 5 A zero sequence current inputs, and 5 A sensitive ground current inputs, as well as four 20-<> mA analog outputs to meet the needs of different industrial automation equipment and systems.

Wide power supply range: Rated control power from 88 to 300 VDC or 70 to 265 VAC @ 48 to 62 Hz, suitable for different power supply environments.

3. Application fields

Power plant: used to monitor and protect the operating status, current, voltage, frequency and other parameters of the generator to ensure the safe and stable operation of the generator.

Generator sets: Applied to independent generator sets, such as standby generator sets or generator sets at remote sites, to monitor the operation of the generator and trigger the corresponding protection and control operations.

Industrial automation systems: Integration with other control devices and systems for remote monitoring and operation of generators.

Power system: Widely used in transmission and distribution systems, monitoring and protecting the generator's connection to the grid, and responding to grid failures, voltage anomalies and other situations.
