Factor Correction Benefits
Causes of Low Power Factor & Utility Surcharges
AC motors, transformers, fans, welding equipment, extruders and injection
machines, presses and stamping equipment as well as ballasted lighting are some
of the many prevalent inductive loads that contribute to a "lagging power
factor" within an electrical delivery system. This translates into wasted energy
and results in higher "demand and distribution" charges being applied by the
supply utility every month. Depending on the “load” size and the power factor
percentage, these surcharges can be very costly. We correct and eliminate
these additional costs!
How Low Power Factor is Corrected.
By installing specially-designed PFC capacitors or reactive power (kvar)
generators into the electrical distribution system. These capacitors will
produce and supplement the reactive power necessary in the operation of all
inductive loads and reduce the amount of kVA drawn from the main transformer and
registered on the meter as "peak demand". Our PFC capacitors have a life expectancy
of 20 years.
Eliminating the Need to Upgrade Your Transformer!
When capacitors are added to the system, the power factor is improved and
the kilowatt (kW) capacity of the system is increased. For example, a 1000 KVA
transformer with a 70% power factor provides 700 kW of power to the main bus.
When capacitors are introduced into the system and the power factor is improved
to 95%, the transformer is then able to provide 950 kW of load into the system.
This could eliminate the necessity of installing a very costly, larger
transformer.
Other Cost Saving Benefits.
Capacitors installed into the system will reduce total current and power. A
20% reduction in current (amperage) will yield 36% reduction in distribution
system losses and lower energy costs by as much as 50%. Lower current draw means
smaller conductors, fuses etc. creating more savings. Voltage levels and
fluctuations will be improved resulting in better equipment performance, longer
life and less breakdowns.
