  • Automatice Power Factor Correction

Now a day’s maximum of industries depends on inductive loads which results is lagging power factor. Everyone knows that how costly electricity has become in present time. Therefore it becomes utmost important to cut down on electrical consumption for reducing expenditure.

Power Factor is the ratio of Active Power (kW) to the Apparent Power (kVA)

Looking at the Beer Mug we can say kVA is the sum of kW and kvar, so,

PROBLEMS DUE TO REACTIVE POWER

The idea of putting capacitive kvar equipment on the same BUS in-order to nullify the effect of inductive kvar is called compensation. Reactive power creates number of problems in the system like,

  1. Direct Billing effect/ Penalty by the Utility Authority
  2. Transformer Heating / Capacity
  3. Cables Heating / Capacity Reduction
  4. Voltage Drops/ Peaks
  5. Generators Capacity Reduction
  6. Flicker

We offer the APFC panel from 50 Kvar to 1000 Kvar for designed for medium to large load network. Our system is very cost effective, very reliable and maintaining the unity power factor. Our system is ready to measure the reactive power to the system through CT’s

Features of APFC:

  1. Micro processor based Neptune 3 Φ P.F controller with inbuilt load analyzer.
  2. Auto/Manual selection switch.
  3. HRC fuse/ MCCB 35kA (optional ) for backup protection of capacitor banks.
  4. Measurement of A, V, PF, Cosφ, W, VAR, VA (ΣW, ΣVA, Σvar etc.)
  5. The consequent switching time between capacitor steps is adjustable from 2 to 50 sec
  6. Automatic calculation of C/k value
  7. The recording shall be carried out in inbuilt data Logger. It is possible to log the data with adjustable time difference of 1 min. to 24 hours
  8. Power range: 50 – 1000 KVAR (440V)
  9. Mains voltage (working voltage): standard 440V (other voltage on request)
  10. The basic structure is made of white CRCA steel sheet with mounting plate Zinc galvanized
