* Applied for Patent
MS-27 Power Savers introduce low-loss impedance path
between the source and the load, which causes
maximum power transfer in the circuit that results in
substantial saving in power consumption.

FAQ’s
FAQ’s
Q.Where do you locate the Energy Saver?
A.For achieving maximum Savings the Energy saver must
be as close as possible to the load point, so that line
drops will be lower.
Q.Can we have single system for 200 KVA & above
A.Energy savers for individual loads are more ideal because
impedance matching is more accurate in such cases and
line losses can be reduced by locating close to the load.
FAQ’s
FAQ’s
Q.If we already have APFC Panel installed do we still need an Energy
Saver?
A.Yes! APFC Panel is a mandatory requirement of SEBs, installed
near the Trivector meter primarily to reduce the Demand. How ever
Energy Saver is installed close to load point and helps reduce the
consumption.
Q.Why do you need a Data Logger?
A.Data Logger helps in monitoring and logging the variation in the
load and helps in load analysis and remedial actions.
FAQ’s
FAQ’s
Q.Can we show savings in all cases?
A.
a) In Low voltage areas Energy saving depends on the load
nature and is not assured
b) When motors are operating at full load the savers may not be
very effective.
c) Electro Mechanical (Traditional Moving Coil) Meters: Though
savings are high actual readings/utility bills do not substantiate
the savings fully.
d) Intermittent operations also may not have effective savings
FAQ’s
FAQ’s
Q.What is the difference between Variable Frequency Drive
(VFD) Savers and Entek Energy Savers?
A. VFD is for Motor Applications only, it varies the frequency
so as to reduce the consumption.
VFD’s introduce harmonics and reduce power factor
Q.How does Electronic ballast compare with “Entek” Power
Saver ?
A. Electronic ballast generates harmonics and induced in the
supply which affects the life of sensitive equipment and it also
reduces the power factor. Entek Power Saver does not
produce any harmonics and improve power factor.
