Specification of Technical Solution and Functions:

• Compact solution including field transformer up to 80 kVA inside one cubicle

• Digital Tenel-AVR one-board microprocessor regulator built on circuits produced by leading manufacturers - INTEL, Thompson, etc

• Compact solution with excit.rectifier, field suppress.., over-volt. protection on semi-cond.modul..

• Possibility of field cubicle completing with complete generator and/or motor protection

• Choice possibility of regulation: Voltage - Power factor - Reactive power - Field current

• Implemented additional functions in AVR: stator and rotor current limiters, protection against machine oversaturation U/f, keeping guard over underexcitation limit

• Stand-by system of generator protections in AVR

• RS 485 serial communication interface by Modbus RTU protocol for connect. to central control

• Possibility of extension of AVR algorithms with auxil. drives control and set appliances control

• Diagnostic functions in AVR making putting into operation and operation checking easier

• Complete measuring of currents, voltages, outputs, power factor on the AVR display

• Fitting of AVR with EEPROM memory for storage of parameters for putting into operation

• Fitting of regulator with history and statistics for operation monitoring and set failure analysis.
