ANIKRON T-07

Digital excitation regulator for synchronous motor ANIKRON T-07 (for static excitation system) is intended to provide power for the excitation winding and automatic control of the excitation currents during startup, synchronous operation and emergency mides of synchronous motors.

Main characteristics:
· Additional control system of the bridge thyristor power rectifier allowing to detect and prevent any possible trouble in thyristor operation
· Opportunity of manual selection and correction of the required control algorithms
· Graphic 10" LCD for viewing of preset and operational parameters of motor and excitation including oscillograms of the main events
· Crate location of the controlling boards that simplifies the maintenance
· Advanced system of data collection and analysis
· 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
· Immediate field suppression after the motor is disabled by forcing the thyristor rectifier to the inverter mode
· Testing (pre-startup) mode that enables to observe the main parameters of the motor and the excitation system
· Wide range of climatic versions and degrees of protection of cabinet assembling
· Rated operation period - 15 years
· Events log capacity no less than 12 000 events
· Oscilloscope capacity no less than 500 oscillograms
