All products

Automatic power factor correction with capacitor banks

Medium voltage automatic power factor correction/reactive power compensation systems using capacitor banks are used everywhere that motors are still directly operated without power electronics, or other consumers with a low inductive cosφ place strain on the grid with reactive power in addition to their active-power requirements. Local supply of this reactive power by means of compensation systems relieves the burden on the supply grid and reduces losses.

M.V Automatic power factor optimizer

Medium voltage automatic power factor optimizer are very beneficial in power grids. They provide the reactive power needed by electrical motors, transformers, etc. This increases the transmission capacity and reduces losses thanks to higher power factors. They enable power factor targets of the utilities to be met. Meanwhile, it also a key component in various filter solutions that reduce harmonic content. They reduce the risk of disturbances in production processes, metering errors and malfunctioning of relay protections. This extends the service life of connected equipment.

SVG Hybrid Active Power Factor Correction system

Static VAR Generator (SVG) Hybrid Active Power Factor Correction system (HAPFCs) is a device connected in parallel with the load to be compensated. The device is a controlled current source which provides a current waveform in real time.

TSC SVG Mixed Power Factor Correction panel

Static VAR Generator (SVG) Mixed Active Power Factor Correction system (HAPFCs) is a device connected in parallel with the load to be compensated. The device is a controlled current source which provides a current waveform in real time.

Power Factor Correction System with Harmonic Filtration

Static VAR Generator (SVG) Hybrid Active Power Factor Correction system (HAPFCs) is a device connected in parallel with the load to be compensated. The device is a controlled current source which provides a current waveform in real time.

Low voltage Advanced Static Var Generator ASVG

The Advanced Static Var Generator provides the same dynamic performance as the SVG with the added benefit of combining harmonic mitigation. Available in 50/100kVar wall mount and 30/50/75/100/150kVar cabinet mount modules, 400/480/690VAC three phase.
