Home >> Products >> APFC Panel Hanut India: APFC Panels [Panels for Automatic Correction & control of Power Factor]
Hanut India offers panels for automatic correction and control of power factor.
Hanut India's APFC panels help customers in maintaining near unity power factor in their
establishments even under varing load conditions.
Investment in APFC panel is a very SMART decision with very high rate of return.
APFC panel protects the customer from poor power factor and associated problems.
Poor power factor leads to following problems:

Excessive kVA demand for a given kW load resulting in higher electricity bill
penalty from the state electricity board
high line currents resulting in high ohmic losses
excessive voltage drops and voltage fluctuation harming the equipment and reducing their efficiency
It is true that a properly designed APFC panel pays back for itself in a very short time span.
Features of Hanut India's APFC panel
* The APFC relay uses intelligent switching algorithm to reduce the number of capacitor bank switching
operations required to attain the required KVAR.
* The intelligent switching algorithm of the power factor control relay also uses the capacitor banks evenly
thereby allowing uniform aging of the capacitors and the contractors.
* APFC relay gives the facility to operate the panel in manual mode in case of special circumstances.
* The APFC panel is liberally sized. This allows for systematic placement of the components and easy
maintenance in future. Panel is designed for indoor use. It is IP41 rated with forced cooling.
* To prevent tampering with the setting of the APFC relay a secondary glass door with sealing knob is
provided to cover the relay.
* A system is as good as the components it is made from. Hanut India uses only branded & high quality
components in its APFC relay panels. For example
APFC relay are from : EPCOS / Schneider / HPL
Capacitor duty contractors [with inrush current limiting circuit] are from: EPCOS / Schneider / EatonPower factor correction capacitors are: Heavy duty models of EPCOS / Schneider
* Thermal management: High temperature is detrimental to the performance and service life of the power
factor correction capacitors. To protect power factor correction capacitors from high temperature they are
optimally placed at the bottom of the cabinet with liberal spacing between the banks. Also one AC 220V
operated exhaust fan is provided in the capacitor bank section to throw out the heat.
* Safety of the electrical equipment and of the maintenance staff have been given top priority while
designing and building the APFC panel. Capacitor manufacturers installation instructions are followed. The
power factor correction capacitors are mounted on a properly earthed stainless steel platform. An
instruction manual for proper usage is supplied with the APFC panel. Contractors, MCBs etc. of
recommened ratings are provided.
* Descriptive alarms: APFC panel generates visual alarms for faults [over & under compensation, over &
under voltage, high THD harmonics in the supply] so that faults can be attended to before serious damage
can take place. Additional 'alarm becon' can be provided on top of the APFC panel to draw the attention of
maintenance staff quickly.
