ANIKRON TM-03 B
The compact digital excitation regulator ANIKRON ТМ-03 B for a synchronous motor, series 03, for brushless excitation systems is intended to provide power for the rotor excitation winding and automatic control of the excitation current during startup, synchronous operation and emergency modes in industrial synchronous motors rated up to 12500 kW and equipped with a brushless excitation system (with brushles exciter) or similar to it.
Main characteristics: 
· Complex programmed control algorithm allowing to maintain excitation control by stator voltage, rotor current, total and reactive current of the stator with the automatic selection at any moment of operation an optimum combination of them
· Recording of the events log and oscillograms of main events to the flash-drive through the USB-port located at the front panel of the excitation regulator
· Automatic calculation of the preset parameters of the excitation after input of the main rated parameters of the motor to the control board
· Fully identical, interchangeable, galvanically decoupled main and backup excitation control units each provided with its own set of power supply units, pickups, and actuation circuits with automatic immediate switch from main to backup unit
· Reactive current control according to the set value and managing of reactive current production or consumption
· Wide range of protection algorithms
· Testing (pre-startup) mode that enables to observe the main parameters of the motor and the excitation system
· Rated operation period - 15 years
· Events log capacity no less than 1000 events
· Oscilloscope capacity no less than 100 oscillograms
