About the 750-P5-G5-S5-HI-A20-R-E
PRODUCT OVERVIEW
The General Electric Feeder Management Relay Model 750-P5-G5-S5-HI-A20-R-E is a microprocessor-based unit designed for the management and protection of electrical power distribution systems. It features a combination of a Motorola 68332 32-bit microprocessor and an Intel 80C186 16-bit microprocessor, providing fast and accurate processing of input and output signals.
The 750-P5-G5-S5-HI-A20-R-E provides primary and backup protection for buses, transformers, and transmission lines. It has a high-voltage power supply that is rated for 88-300Vdc and 70-265Vac at a frequency range of 48-62 Hz. The relay unit features 5 A phase current inputs, 5 A zero-sequence current inputs, and a 5 A sensitive ground current input for enhanced protection.
KEY FEATURES
One of the key features of this relay unit is its enhanced display, which provides clear and concise information about the electrical system being monitored. The display includes a "Breaker Closed" LED indicator, which illuminates red to indicate when a breaker is closed. This helps to ensure that the electrical system is functioning properly and that power is being delivered to the intended areas.
In addition to its display, the relay unit has eight 4-20 mA analog outputs. These outputs can be used to control external devices, such as breakers or relays, based on the status of the electrical system. This allows the 750-P5-G5-S5-HI-A20-R-E relay unit to serve as a control center for the power distribution system, allowing for a fast and accurate response to changes in system conditions.
