L90-J07-HLH-F8L-H6P-L6N-N6P-SXX-UXX-W7J

Product Description

Boasting a combination of monitoring, metering, and safeguarding capabilities in one compact unit, GE Multilin’s L90-J07-HLH-F8L-H6P-L6N-N6P-SXX-UXX-W7J is a Line Current Differential System compatible with overhead and underground cables, circuits with trapped transformer feeders, and dual and single-breaker circuits that need autoreclosing and synchrocheck features. The relay works with lines of any voltage, and all collected data and events detected by the relay are stored for later review.

The relay’s RS232 port situated on the faceplate allows users to connect the unit to a computer running Multilin’s EnerVista UR software program, which considerably simplifies and accelerates user interactions with the system. EnerVista UR offers a suite of useful tools, including Viewpoint Engineer, Viewpoint Monitoring, Viewpoint Maintenance, and the EnerVista Integrator. The EnerVista integrator enables a stress-free integration of the relay into new or existing systems; it utilizes automatic event retrieval, automatic waveform retrieval, and downloads recent Multilin drivers in order to get the unit up and running as fast as possible. The Viewpoint Engineer tool provides a drag-and-drop interface for easy configuration and testing or the L90-J07-HLH-F8L-H6P-L6N-N6P-SXX-UXX-W7J.

The L90-J07-HLH-F8L-H6P-L6N-N6P-SXX-UXX-W7J employs GOOSE (generic object-oriented substation events) messages to eliminate hardwiring and allow for peer-to-peer wireless communication between devices. This replaces expensive copper connections, reducing installation time and costs for the user. GOOSE messages occur when a value change is detected, and the messages are retransmitted several times to ensure they reach their intended target within the system. GOOSE messages are time tagged and contain vital data.
