Introduction
iSaver Manual
This manual is intended as a general guide for the installation, commissioning, maintenance, and troubleshooting of
iSaver DPFC (Dynamic Power Factor Control) units.
This manual is written for qualified and licensed personnel exclusively. It is not a substitute for
professional training, safety and hazard procedures, or for handling industrial equipment. This
equipment must be installed as per applicable Canadian standards, Regulations and National
wiring rules. This is essential to avoid electric shock or fire resulting in personal injury and damage
to equipment. Improper connection, handling, or installation may cause malfunction and potential
damage.
After going through the contents of this manual, if there are any doubts with regard to connectivity, commissioning,
operation or any other subject, it should be clarified with the authorized representative of the supplier. EnCorp
does not accept any responsibility for any damage (direct or indirect, consequential loss) incurred due to improper
installation or use of this unit(s).
Special Precautions
The following are mandatory safety measures when installing or using iSaver equipment:
• Measure the electrical parameters to ensure that the unit selected is appropriately sized and suitable.
• The standard iSaver units are designed for indoor use only and should be installed in a secure, dry environment.
• During transportation from the manufacturing unit to the customer’s premises, there is always a chance of
some connections within the unit becoming loose. It is mandatory to internally inspect the unit and tighten any
loose connections prior to installation and start-up.
• Depending on the environment and site conditions, the unit should be periodically inspected internally by a
qualified electrical technician.
Introduction
Majority of the loads in commercial establishments & industrial processes have very rapidly changing loads due to the
nature of their operation. These are usually complex loads highly inductive in nature as they use induction motor
drives, AC/DC drives, Arc Furnaces, Welders, CNC machines, Sodium Vapor / Metal Halide / Fluorescent lightings,
etc.
Though there are also some resistive and potentially some capacitive loads, the overall nature of this electrical load is
complex inductive load. This complex inductive load causes a poor lagging power factor. If this poor power factor is
left uncorrected, it draws excessive current (kVA) than the required amount to perform useful work. As Utilities have
to provide for the high demand which also effects their operations and distribution, they usually impose one or several
charges if the electrical efficiency of the end user is lower than their contracted value. Depending on the tariff structure
of the individual, this may increase their electricity bill and reduce available capacity substantially. As a consequence of
low efficiency, the customer may get charged for high demand offtake, reactive power charges, power factor penalties
etc. The increased current due to low efficiency also effects the installed capacity utilization of the facility.
Using iSaver DPFC (Dynamic Power Factor Corrector), electrical efficiency is enhanced almost to 100% and
consequently the monthly Electricity bill* is substantially reduced.
