Basler Electric BE 13693 002 Transformer

An economical, microprocessor-based relay designed to replace out of date,

aging electromechanical relays, with models to replace existing GE and ABB

relays with no wiring changes. Basler Electric also offers the BE1-79A in an S1

case for new installations.

A terminal voltage limiter within the IFM-150 can be enabled to

monitor the generator voltage through the  synchronizing

transformer or external voltage transducer and compare the

measurement with a user adjustable reference level.

If the generator voltage exceeds the reference level for a user

-adjustable amount of time, the IFM-150 will modify the SCR

firing pulses and limit the generator voltage.

The BE1-CDS240 Current Differential System is an economical,

microprocessor based, multifunction system that provides a four

input, three-phase percentage differential with harmonic restraint

protection.

Also included is three-phase with voltage control, ground, and

negative-sequence overcurrent protection, voltage and frequency

protection, breaker failure for up to four breakers, breaker monitoring

for four breakers, transformer monitoring, and metering functions,

all in an integrated system with several communications options.

The BE1-CDS240 Current Differential System is intended for use in

any low impedance current differential protection application including

transformer, generator, motor, and bus protection.

Four setting groups are provided for adaptive relaying with automatic

selection logic for cold load pickup and/or dynamic setting group changes.

The BE1-CDS240 can be ordered with 12 programmable contact sensing

inputs, 10 programmable outputs, and one alarm output or eight

programmable contact-sensing inputs, 14 programmable outputs and

one alarm output. Outputs can be assigned various functions by logical

programming to perform protection, control, or indicate operations.
