Series PFC Modules The power factor correction of electrical loads is a common problem to
almost all the industrial sector. Most to the loads draw a certain
quantity of active power together with reactive power from the mains.
The Active power (KW) actually performs the work whereas the reactive
power (KVAr) could be interpreted as an undesirable burden on the
supply. The increased flow of reactive power has following
disadvantages, Overloading of power source i.e. Transformer or
Alternator.Higher voltage drops throughout the system.
Standard Features of The Foremost PFC
- Automation self-adjustment to any capacitor step value.
- Allows manual switching of each capacitor steps.
- Digital indication of power factor preset parameters and specified installation data.
- No- volt release feature to immediately disconnect all capacitor in the even of power failure for more than 35msecs.
- Digital setting of individual parameters including target power factor Switching time, step limit etc.
- Elimination of defective capacitors and their indication.
- Digital reading facility of switching cycles per capacitor steps.
- Digital encoded reading of capacity sizes.
- Visual display of harmonic overload alarm.
- Visual display of target cos F alarm.S
- Stage indication of steps switched in, as well as total banks in operation.
- Easy plug in back panel terminal connection.
- Protection against capacitor over current, due to over voltage,
short circuit, system resonance and presence of higher value of
harmonics in the system.
- Digital display of voltage, Currents, KW, KV Ar, KWh, and Frequency.
