Basler Electric BE146N Negative Sequence Overcurrent Relay

The SR8A Retrofit Voltage Regulator is an economical, direct replacement

for existing Basler Electric SR8A voltage regulators. Designed for brush

and brushless synchronous generators, it delivers precise voltage regulation,

fast response times, and dependable excitation control while fitting within

the same mounting footprint as the original SR regulator.

The retrofit package incorporates a modern AVC125-10 voltage regulator and,

where required, an internal sensing module, simplifying installation and

minimizing downtime.

Engineered for reliability in demanding power generation applications, the

SR8A Retrofit supports single- or three-phase sensing, voltage matching,

reactive droop compensation, line drop compensation, and underfrequency

protection. Its rugged design withstands harsh industrial environments,

while compatibility with accessories such as excitation limiters, power factor

controllers, and auto synchronizers makes it a versatile solution for generator

upgrades and modernization projects.

The SR and SSR Retrofit Voltage Regulators are designed as economical,

direct replacement solutions for legacy Basler SR and SSR voltage regulators.

Engineered for quick installation, these retrofit kits fit into the existing

mounting space and utilize terminal-to-terminal wiring to simplify field

replacement. Integrated CT input burden matching supports paralleling

systems with cross-current compensation, while accessory inputs provide

compatibility with var/power factor controllers and excitation limiters.

The SR and SSR Retrofit series delivers the same dependable performance

as the original regulators while helping extend the life and reliability of

generator excitation systems.

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.
