SECTION 1 • GENERAL INFORMATION

Purpose

The BE1-79M Multiple Shot Reclosing Relay automatically recloses circuit breakers, which 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 BE1-79M 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 Loading - decreases likelihood of loss of line.

Application

Four major factors should be considered when establishing a reclosing philosophy.

• Desired number of reclosure attempts.

• Time delay between breaker opening and reclosure.

• Supervisory control.

• System coordination.

The first major factor is the desired number of reclosure attempts. Where most faults are attributable to
heavy tree exposure, as in distribution networks, multiple reclosure attempts are common. This is
possible because of low voltage levels and is desirable considering customer inconvenience during
outages. The BE1-79M is programmable for up to four reclosure attempts per sequence. This allows
tailoring of the reclosing sequence to the specific needs of the circuit.

The second major factor is the time delay between breaker opening and reclosure. On subtransmission
and distribution networks, it is necessary to ensure that motors are no longer running and that local
generation is off-line prior to attempting reclosure. At the same time, a rapid reclosure minimizes damage,
ionization, and system shock in transmission networks. After the first reclosure attempt, additional
attempts are generally delayed to allow for de-ionization of the interrupter. The BE1-79M incorporates one
instantaneous reclosing attempt with bypass capability, and up to three individually adjustable, time­delayed, reclosing attempts.

A third major factor to be considered in reclosing is supervisory control. Supervisory control allows the
operator to maintain control of the system at all times. The BE1-79M has inputs available to bypass the
instantaneous reclose attempt and to drive the relay to LOCKOUT inhibiting relay operation at any time.
In addition, a separate input is available which may be used to initiate a pilot reclosing sequence.

The fourth major factor is system coordination. The BE1-79M has outputs available which may be used to
block or enable instantaneous tripping of the circuit breaker and block a transformer's automatic load tap
changer operation during a reclosing sequence.

9170100990 Rev N BE1-79M General Information 1-1

Model and Style Number

The electrical characteristics and operational features included in a specific relay are defined by a
combination of letters and numbers, which constitutes the device's style number. The style number
together with the model number describe the features and options in a particular device and appear on
the front panel, drawout cradle and inside the case assembly. The model number BE1-79M designates
the relay as a Basler Electric, Class 100, Multiple Shot Reclosing Relay. The BE1-79M style chart is
shown in Figure 1-1.

Style Number Example

The following style number identification chart illustrates the features and options for BE1-79M relays. For
example, if the style number were BE1-79M B6A A6J C0L0F, the device would have the following
features:

BE1-79M Model Number
B Multiple shot
6 Lockout and reset with reclose fail and maximum cycle
A Instantaneous trip enable
A6 Reclose time delay adjustable from 0.1 to 99.9 seconds
J Operating power derived from 125 Vdc or 120 Vac source
C Reset time delay adjustable from 10 to 1000 seconds
0 Standard contact assignment
L Non-isolated contact sensing
0 No option 3 available
F Semi-flush mounting

Style Number Change

Effective November 18, 1991 (serial number 2812 and subsequent), the BE1-79M Multiple Shot
Reclosing Relay, style number identification for multiple shot is changed from A to B. This style number
change was made to differentiate relays with sensing input power module on the outside of the case
(style number A) and relays with the sensing input power module inside the case (style number B).
Section 7 of this manual provides difference data for style number A relays.

Compatibility

Relays with style number B are backwards compatible. That is, they may be used in place of relays with
style number A. The only exception is for a relay with a type Z power supply (250 Vdc/230 Vac) and
isolated sensing. For details, see section 7 of this manual.

Relays with style number A are NOT forward compatible. They may NOT be used in place of relays with
style number B.

Timing

The contact sensing circuits require user-supplied contacts with a
minimum rating of 0.025 A at 250 Vdc. Sensing current is supplied by
the relay in styles with isolated sensing. Styles with non-isolated
sensing require an applied sensing voltage equal to the relay dc power
supply input rating. Burden per contact for non­dependent on power supply type, is listed in Table 1-1.

Refer to Table 1-2.

Output contacts are rated as follows:
