SECTION 1 • GENERAL INFORMATION

Description

The BE1-79A Reclosing Relay is an economical, microprocessor-based relay that automatically recloses circuit breakers that have been tripped by protective relays or other devices in power transmission and distribution systems. The BE1-79A offers true "plug and play" convenience; it can be installed in an existing GE type S2 case with no wiring changes required. General Electric type ACR11A, ACR11B, ACR11C, ACR11E, and ACR11F reclosing relays can be directly replaced by the BE1-79A-100 or BE179A-101. The BE1-79A-200 and BE1-79A-201 are available in a shorter cradle that fits in a Basler S1 case for new installations.

Table 1-1 lists the case style and special features of each version of the BE1-79A.

Features

BE1-79A Multiple Shot Reclosing Relays have the following standard features:

• Rugged construction in a steel, draw-out case

• A maximum of four automatic reclosures

• A maximum of four automatic resets

• Lockout function

• Selectable instantaneous or delayed first reclosure

• Selectable internal or external instantaneous jumper

• Selectable normally closed or normally open RS output contact

• Selectable Relay Fail or Lockout and Relay Fail output contact

• Selectable contact sensing voltage range

Controls and Indicators

The front panel has indicators to verify relay power and recloser status. A Reset switch is provided to restore the relay to the reset mode by clearing a reclosing sequence or a lockout condition. The left side of the relay cradle has switches (S1, S2, and S3) to configure the relay for either ACR11A or ACR11B operation. The right side of the cradle has a switch (S4) to select either an internal or an external jumper for an instantaneous, first reclose. The right side of the cradle also has a switch (S5) to select either normally open or normally closed operation of the RS contact.

Communication

All relay settings are read or changed through the serial port located on the front panel. The BE1-79A uses ASCII protocol.

Power Holdup Circuit

The BE1-79A is available with an optional, internal, power holdup circuit. This circuitry maintains the output contacts for a minimum of 40 cycles after nominal operating power is removed from relay terminals 5 and 6.

Primary Application

The BE1-79A automatically recloses circuit breakers that have been tripped by protective relays or other devices in power transmission and distribution systems.

Over 90% of faults occurring on overhead lines may be cleared by momentarily de-energizing the line. Once the circuit breaker has been opened to de-energize the line, the BE1-79A provides a reliable automatic reclosure. The advantages are:

• Improved service continuity—returns the line to service quickly, preserving line integrity, and minimizing outage effects on critical loads.

• System stability—prevents disjointing of the system grid.

• Higher line availability—decreases likelihood of permanent loss of line.
