- These products are applied for power supply to the winding of synchronous unit excitation (motor, turbo- and hydro-generators of low power) with automatically controlled rectified current in normal and emergency conditions.
- Excitation systems series СТ-СМ and СТ-СН provide:
– Automatic adjustment of voltage, manual adjustments of excitation current, power factor and reactive power adjustment;
– Direct or reactive motor start;
– Generator start with self-synchronization;
– Protection of synchronous unit;
– Signal for machine disconnection from the power net at internal damages of the excitation system;
– Logical operations at start and electrical braking of hydro-generators;
– Connection with upper level through an interface agreed with customer.
