Power transfer relays

Main functions of a power transfer relay:

Main source supply monitoring.
Directing the signal to start the diesel generator set (backup power supply)
Shifting the load to the backup power supply.
Directing the signal to return to the main power supply.
Shifting the load to the mains supply.
Disconnection time delay allowing the diesel generator set to cool down before disconnection.

Power transfer relay GTEC

Power transfer relay GTEC is intended for monitoring the mains condition, the switching on of a backup power supply and the load distribution
Certified in accordance with IEC standards
Amperage ranges from 63 to 1250 A
Voltage between lines exceeds 480 V
Control system voltage of 12 or 24 V of direct current
Suggested 2 / 3 / 4 polar configuration

Power transfer relay GTEC characteristics

Microprocessor control - All the unit control functions are performed by a microprocessor Managing the functions, settings and adjustments are performed programmatically
Improved mechanism of switching power supply sources
Mechanical blocking - mechanical blocking prevents switching the electric power supply from different sources by means of power cables or control system cables
Manual operation mode - there is the possibility of manual switching in case of power supply cutoff
Convenient service / access - the control system is mounted on the door, there is convenient access to all components of a power transfer relay
Power transfer relay allows switching the consumer to various available electric power sources without the interference of an operator
The controller monitors the voltage and frequency of every source. Power transfer relay is used for switching Mains - Diesel Generator Set power supplies

GTEC provides the following functions:

Transmitting the signal on the diesel generator set shutdown
