Cyclic Load Energy Saver with Micro Computer
INTRODUCTION

CYCLIC LOAD ENERGY SAVER is an equipment developed to save power on variable load machines like press Machines, Injection Moulding Machines, Agitators, Conveyors and Textile Mills etc. This unit save power during the noload or partial load periods using delta to start change over and the power saving can be up to 30 To 40% of the noload power. The amount invested can be realised in few months.
CYCLIC LOAD ENERGY SAVER
PRINCIPLE OF OPERATION
During partial load or no-load period motor is supplied with 400/440v as that much power can be saved. Normally motors run in delta mode. l .e. full voltage is applied to the motor. So by making the motor to run in start mode during these no-load only 1/v3 times the line voltage is applied to the each phase winding of the motor which reduces the power input to the motor.
Digital ammeter with auto scanner for three phase currents
Motor protection: over load, single phasing un balanced etc
Individual fault annunciation: ol-over load, spp-single phasing, ub-unbalance
Optional features like star-delta timer
Available in wide range up to 500 A
Man-machine interface through keypad & display
Less heating of motor assuring increase in life
In start mode save energy and obtain higher power factor & lower max. demand
Possible to save between 10 to 20 units per day
The saving in terms of rupees will work out to between Rs.20,000/- to 50,000/-
Low cost & best payback period as low as 6 months
Advantage of 100% depreciation provision in cash flow situation
Provides different curves as 2.5C, 5C 10C for accurate overload tripping on the basis of starting time current of the motor
SCOPE FOR SAVING
Following table shows the scope for saving energy for the motors of different capacity ranges at different loads. The actual values will vary motor and the savings can be higher or lower depending upon electrical and mechanical condition of the motor.
