Basler Electric 2D80367G23 DXCB De-Excitation Module 1200V 5000A Excite

BE1-BPR Breaker Protection Relays are three-phase and neutral, 

microprocessor based relays designed to provide power systems 

with protection and security against monitored breaker failure or

to initiate multiple shot breaker reclosings.

These relays incorporate a powerful means of programming internal

relay logic to satisfy a wide range of user requirements without making

any relay hardware changes. Microprocessor-based design provides

the basic features of a programmable logic controller (PLC) combined

with an instantaneous overcurrent module.

Cased in a 19 inch rack-mount or a vertical panel mount, the relay offers

installation versatility. A wide temperature, 2 lines by 16 character display

provides diagnostic and setup information. Two RS-232 serial ports (one

each front and rear) and one RS-485 serial port (rear) provide remote

communication and relay control.

Built-in diagnostics and monitoring features provide information for both

the health of the relay and the health of the breaker being monitored.

Relay diagnostics include continuous background monitoring of the

power supplies, analog-to-digital (A/D) converter, random-access memory

(RAM), read-only memory (ROM), and electrically-erasable programmable

ROM (EEPROM). A dedicated alarm (ALM) relay output provides power 

supply, microprocessor, and software alarm status. Breaker diagnostics

include a timing diagnostic log, breaker contact duty monitoring, breaker

resistor protection, and breaker arc detection.

Other monitoring features include oscillographic fault records and fault

summary logs. BE1-BPR relays use the Inter-Range Instrumentation Group

(IRIG), Format B for high timing accuracy and resolution.

Mounting Hardware

The AVC Sensing Module can be mounted directly on a genset using #10-32 or

equivalent hardware. A lock washer should be used between the screw head and

body of the module. Torque applied when tightening the mounting hardware

should not exceed 25 inch-pounds (2.8 N•m).

The AVC Sensing Module provides a convenient and cost-effective method

for expanding the applications where AVC63-12 and AVC125-10 voltage

regulators can be applied. The AVC Sensing Module increases the nominal

sensing voltage of style BX AVC63-12 and AVC125-10 voltage regulators

from 200/240 Vac to 480 Vac or 600 Vac. The AVC Sensing Module is

compatible with nominal sensing frequencies of 50/60 Hz and 400 Hz.

A compact, rugged (potted) case enables the AVC Sensing Module to be

mounted directly on the generator.

Other than making connections during installation, the AVC Sensing Module

requires no adjustment or calibration.

The AVC Sensing Module is housed in a potted, plastic case that can be

mounted in any convenient position.

Overall module dimensions and panel drilling dimensions are illustrated in Figure 1.

CONNECTIONS

All AVC Sensing Module connections are located on the back panel. Sensing voltage

is applied to the lower, six position terminal block. Sensing voltage is supplied to the

voltage regulator from the upper, three-position terminal block. Connections consist

of #6 terminal screws. Each terminal accepts a maximum wire size of 12 AWG (13

mm2). When securing connections, apply no more than 9 in-lb (1 N•m) of torque to

each terminal screw.

Before connecting the module, review the terminal descriptions listed in Table 1 and

the connection diagram of Figure 2. At any given time, only one of the two sets of 

sensing voltage input terminals can be used. Under no circumstance can both the

480 Vac and 600 Vac sensing input terminals be connected to a voltage source.
