SIMPLE SOLUTIONS TO COMBAT RISING ELECTRICITY COSTS
Data
Interpretation
Solution
Quality of supply
High or low voltage supply outside of the 10% to 15%
of the set boundaries can cause pre-mature ageing,
pre-heating or malfunctioning of the equipment.
Installation of a Power Quality Analizer for a period
of 7 days will determine the nature of supply,
therefore will take up supply authority or installation
of a mains stabiliser or UPS.
Load spikes
Unscheduled or simultaneous switching ON of the load.
Pre-determined sequence start up of various
loads that will prevent high spikes and will
therefore reduce kVA charge.
Harmonics
The invisible enemy! Presence of harmful harmonics
from such sources as UPSs and VSDs can reduce the
life of electrical equipment as well as excess current
in Neutrals.
Unbalanced Load
Exessive load being placed on a single phase
Power Factor
Typically, inductive loads such as motors (including
air conditioners) cause the electrical sytem in your
office building or factory to run inefficiently, reducing
your available power from your minisub or sub-station
supply and waste electricity costs by up to 20%. Every
month!
While this catalogue focuses on the above, the other key areas include:
1.
2.
3.
4.
Lighting, use efficient light sources and reduce kw demand.
Insulation, heating and ventilation.
Improving efficiency of motors with soft starts and variable speed drives.
Supplementing grid power with solar and or wind energy.
Finaly ... to make all this straight foward, ACDC Dynamics has formed a
specialised company, ACDC Green Energy Solutions, to do everything for
you - even to the extent of providing off-balance sheet rental solutions.

These can be managed by filtering them out using
special chokes, typically included within the PFC
system. Harmonic chokes are an additional expense
which is amply covered by the extended life of
electrical equipment.
Installation of Power Analizer in order to determin
load per phase. The re-positioning of the loads will
assist with reducing max demand (kVA) charge.
By connecting capacitors to your system, the power
factor is corrected. For a single motor, a fixed
capacitor will do. However, for varying loads, a
system is required to switch capacitors in and out of
the sytem, these are automatic Power Factor
Correction systems. (PFC). These usually pay for
themselves between 9 and 18 months.

Passive Power Factor Correction
ES15
ES100
Power Factor Correction (PFC) is a technique of counteracting the undesirable effects of electric loads that create a power factor less than one.
This range of passive (PFC) units can save 10%-20% of energy consumpion.

kVAr Selection formula: kWx Factor required = kVAr required
Example:
Load of 400kVA at 0.7PF, correct to 0.96PF
From the above table factor is 0.729
Convert kVA to kW (Useful Power): kva x PF = kW
400 x 0.7 = 280kW (usefull power)
Therefore size of capacitance required:
Useful Power (kW) x Factor = kVar
280 x 0.729 = 204.1kVAr
