Reactive Power?
We know that reactive loads such as inductors and capacitors dissipate zero power, yet the fact that they drop voltage and draw current gives the deceptive impression that they actuallyA�dodissipate power. This a�?phantom powera�? is calledA�reactive power, and it is measured in a unit calledA�Volt-Amps-ReactiveA�(VAR), rather than watts.

Why it is essential?
Motors, transformers and other inductive loads require reactive power. Transmitting/distributing the reactive power from the power station to the loads is uneconomical. It impose undue burden on generators and transmission/ distribution system, causes additional losses, increases, voltage drop and the overall power requirement of the plant.
Economic and technical reasons thus make it expedient to relieve the generators, transmission/distribution system and able of reactive power. The automatically controlled capacitors i.e. Powermann power factor improvement (PFI) plant is well suited for this purpose.

Correction/Improvement Principal

Powermann power factor improvement plants are manufactured in modular design and consist of-
– relay module
– capacitor modules
The regulation module consist of-
– solid state reactive power relay with digital indication of power factor
– circuit breaker for control cable protection
The capacitor module consist of-
– air break contactors to switch capacitors
– dry power capacitors (insulating gas filled) conforming to IEC 70, IEC 831 (lates specification) EN 60831-1 with
– metallized plastic foil
– low loss (0.2W / KVAR) polypropylene dielectrics that allows self healing
– environment friendly insole device
– harmonic load tolerance
– high reliability ting gas filled
– built-in over pressure relief
– high overload capacity (15 X rated current)
– high capacitance stability
– long life (Approx 100,000 hrs.)
– high switching durability
– high temperature class
– touch proof terminals
