Product Description

Armed with advanced disturbance and fault recording, General Electric Multilin’s L90-G00-HCH-F8F-H6P-LXX-NXX-SXX-UXX-W7D is a Line Current Differential System and part of the Universal Relays series. The relay can work with circuits with tapped transformer feeders, overhead lines, three terminal line configurations, and distributed busbars. 

In addition to aforementioned event recording features, this unit has a number of control and protection features such as thermal protection, segregated current differential protection, under/overfrequency protection, under/overvoltage protection, ground distance protection, phase reversal, thermal overload protection, and more. The segregated current differential protection feature can detect faults within a half cycle and uses advanced algorithms to stabilize issues related to bandwidth, sensitivity, and dependability that other relays may struggle with.

GE’s L90-G00-HCH-F8F-H6P-LXX-NXX-SXX-UXX-W7D offers a plethora of communications functions. The RS232, RS422, RS485, and Ethernet networking interfaces provide interrelay communication options as well as communications with computers running Multilin’s industry-leading EnerVista software. The relay also offers multiple communications protocols, including IEC61850, DNP 3.0 Level 2, Modbus RTU, Modbus TCP/IP, and IEC60870-5-104.

Frequently Asked Questions about L90-G00-HCH-F8F-H6P-LXX-NXX-SXX-UXX-W7D

What are the current differential protection characteristics of the UR series Universal Relay Multilin L90-G00-HCH-F8F-H6P-LXX-NXX-SXX-UXX-W7D?
The Multilin L90 is a member of the universal relay GE Multilin series (UR series) and functions as a line current differential system. The L90 is able to protect high-speed line current differentials from a wide range of voltage specifications while functioning to provide total distance protection and dual-breaker application. This feature is applicable to single and three-pole applications. In order to do so, the Multilin L90 samples at each relay point to minimize communication complications. 
What are the monitoring and metering specifics of the UR series Multilin L90?
The L90 Multilin line differential relay has key monitoring features that include an ability to monitor remote, differential per-phase, and local currents in real time. Additionally, the oscillography is characterized by 64 samples per cycle with up to a 64 record capacity. The L90 can record up to 1024 time characterized events with a 0.5 ms scan of the digital inputs. The data logger contains up to 16 channels with a sampling rate that is user specified. The multi-end fault location is advertised at a 2% accuracy. These monitoring and metering features allow the L90 to be ideal as a line current differential Multilin system.
