Shunt Capacitor

NEEP OF CAPACITORS
In electrical system A.C. inductive loads consume active power and also reactive power. This reactive power is needed to generate magnetic field for inductive loads.

The reactive power necessary to achieve a P.F. is calculated as under:

Look at the Logical approach –

ADVANTAGEDS OF POWER CAPACITORS

• Reduction in systems losses.
• Improvement in voltage level.
• Lower maximum KVA demand.
• More power for the same KVA.
• Save power and save money.

Thus resulting in lower power consumption leading to lower electricity bill.

APFC PANELS

CONTRACTOR SWITCHED TYPE SYSTEMS

Application

• Light & large scale industries .
• Power Utilities.
• Upto 10% harmonic distortion.

THYRISTOR SWITCHED TYPE SYSTEMS

In a modem industrial set up with rapid changing loads, thyristor switched capacitor panel ensures that capacitors are switched on & off precisely at zero inrush current while simultaneously revolutionizing the P.F. correction system with the ability for practically unlimited no. of switching operations.

Application

• Light & heavy load industries.
• Steel Industries.
• Foundries.
• Electricity Utilities.

DETUNED APFC SYSTEM FOR HARMONIC LOADS

Automatic detuned filter bank is used where harmonic distribution is more. Capacitor step with blocking reactor, forms resonant circuits tuned to frequency below dominant harmonic i.e. 5th, 3rd. This avoids harmonic amplification. It also removes certain amount of harmonic currents. Detuned filters are manufactured having frequency 130 Hz, 141 Hz and 189 Hz.

Application

• Steel Plants, Foundries.
• Electrolysis Plants.

Other Products

• HT Power Capacitors.
• Harmonic Filters.
• Surge Capacitors.
• We take up complete installation and commissioning of APFC panels/substations.
