Power Savers

Effect of Voltage variation on lamps* Lamp 10% Lower Voltage 10% Higher Voltage Fluorescent Tube lights Light output Decreases by 9% Increases by 8% Power Input Decreases by 15% Increases by 18% HPMV Lamps Light output Decreases by 20% Increases by 20% Power Input Decreases by 16% Increases by 16% HPSV Lamps Light output Decreases by 30% Increases by 30% Power Input Decreases by 24% Increases by 26% *Source: Bureau of Energy Efficiency Hence Voltage reduction is not the real solution, we need optimum voltage

Operation Principle * 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.

Operation Principle Maximum power transfer through impedance matching & Optimum Voltage Rv: Motor IV Curve Variable Impedance Ri Internal Impedance Load Current Vo + _ Voltage

Operation Principle Voltage Vs Current Waveforms for different loads For Pure resistive loads current is in phase with voltage. For Capacitive loads current leads the voltage.

Operation Principle KW (Active Power) KVA (Total Power) PF = KW ___ = Cos KVA KW, KVAR & KVA Vector KVAR (Reactive Power)

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 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 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 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.
