Posted by ecsanyi on Wednesday, June 16, at The relay also abb ref 615 optional high impedance fault HIZ and sensitive earth fault SEF protection for grounded and ungrounded distribution systems.
Also, the relay incorporates a flexible three-phase multi-shot auto-reclose function for automatic feeder restoration in temporary faults abb ref 615 overhead lines. Enhanced with safety options, the relay offers a three-channel arc-fault detection system for supervision of the switchgear circuit breaker, cable and busbar compartments.

To protect the relay from unauthorized access and to maintain the integrity of information, the relay has been provided with a four-level, role-based user authentication system, with individual passwords for the viewer, operator, engineer and administrator level.
The relay abb ref 615 supports the industry standard DNP3. The substation configuration language enables the use of engineering tools for automated configuration, commissioning and maintenance of substation devices.
Applying GOOSE communication to the REF relays of the incoming and outgoing feeders of a substation, a stable, reliable and high-speed bus protection system can be realized.
The cost-effective GOOSE-based bus protection is obtained just by configuring the relays and the operational availability of the protection is assured by continuous supervision of the protection relays and their GOOSE abb ref 615 over the station communication network.
Depending on the chosen device configuration, the relay monitors the wear and tear of the circuit breaker, the spring charging time of the CB operating mechanism and the gas abb ref 615 of the breaker chambers.
The relay also supervises the breaker travel time and the number of CB operations to provide basic information for scheduling CB maintenance.
Rapid set-up and commissioning Since REF is designed specially for feeder protection, it can be rapidly set up and commissioned, once it has been given the application specific relay settings. It also offers the abb ref 615 to be adapted to meet the particular requirements of an individual application.
Unique plug-in design relay The plug-in type relay design speeds up installation and testing of the protection.

The factory-tested relay units can be withdrawn from the relay cases during switchgear factory and commissioning tests. The plug-in design abb ref 615 speeds up maintenance work thanks to the easy exchange of relay units.
The relay case provides automatic short circuiting of the CT secondary circuits to prevent hazardous voltages from arising in the CT circuits when a relay plug-in unit is withdrawn from its case. The pull-out handle abb ref 615 the relay unit into its case can be sealed to prevent the unit from being unintentionally withdrawn from the relay case.
