Power is the basic necessity for the economic
development of a country. The power should be handled in an efficient manner to
meet the power requirement. This project presents the effective usage of star –
delta starter in a power saving way in particular applications. Delta star
Converter Module is the system to be interfaced with the existing Star Delta
starter. When the load on the motor is less than 50% of full load, it switches
the motor to operate in STAR to SAVE ENERGY. When the load increases beyond
50%, it automatically switches the motor to operate in DELTA without disturbing
the working of motor. This module is recommended for applications where load
changes are not too fast. This is suitable for any capacity motor by using
appropriate Current Transformer and calibrating the same.
By implementing this project we can achieve, ·
industries, more than 80% of the motors are AC induction motors. An induction motor used can be single phase,
poly-phase(3-phase), brushed or brushless. Since in industries 70% of the AC motor are three phase induction
motor so, we have to concentrate on energy saving in this area. Here, in this
project a proposal for energy saving in 3-phase induction motors is put forth.
