Three Phase Power Line (Input) Reactor For VFD's

Coilmag’s Control Transformers are Isolation Transformers designed to provide a high degree of secondary voltage stability (regulation) during a brief period of overload condition (also referred to as “inrush current”). These units are also known as Machine Tool Transformers, Industrial Control Transformers or Control Power Transformers

Reactor is placed before VFD / Thyristor drive for protecting from harmonics and di/dt effects, and for the following benefits:

  • Mitigation of harmonics to the power supply line.
  • Mitigation from inrush current, due to process load requirements.
  • Mitigation of electrical noises to the power supply grid.
