General Electric Multilin’s 750-P5-G5-S5-HI-A20-R is a Feeder Distribution Protection Relay intended to manage and safeguard distribution systems. The relay has an approximate with of seven inches, an approximate length of six and a half inches, and an approximate height of eight and a half inches. The relay can be mounted on a standard 19-inch panel. It comes with the SR 750 series chassis, which features a dust protective door and drawout construction.
The 750-P5-G5-S5-HI-A20-R helps eliminate the need for additional monitoring and metering equipment, as the relay itself has multiple built-in monitoring capabilities:
Trip Counter: The relay records the number of breaker trip operations, and can display this value on the unit’s 40-character alphanumeric LCD or within the EnerVista 750 software program.
Metering: The 750-P5-G5-S5-HI-A20-R can precisely measure voltage, amperes, watthour costs, frequency, and more.
Oscillography: AC input voltages and current can be sampled and stored by the relay, along with the current statuses of output relays and logic inputs. The amount of data recorded is configurable by the user, and the recording process initiation parameters can be adjusted as well.
Data Logging: Users can set the monitoring and data recording of a given system parameter. The time between each capture is also adjustable.
These features reduce troubleshooting times and simplify the connections of distribution feeder systems. They can also suggest when preventative maintenance is required to lessen downtime and prolong system life.
