REASON OF FAILURE ON MOTOR LOAD : Electrical equipment’s are designed for 240 volts (single phase) or 415 volts (3-phase) and operate with optimum efficiency at its rated voltage. 90% of industrial load consists of motors. Electric motor (particularly smaller capacity motors up to 7.5 H.P.) draws considerably high current at high voltage and increases energy consumption, increases MDI and reduces power factor etc. These excessive power losses of motors generated at higher voltage results in premature failure of electrical equipment’s. Also after the rewinding of motor its efficiency reduced by 3-5% and you have to replace the motor with new one after 2/3 times rewinding.

Energy Savings : The energy savings achieved by voltage optimisation are an aggregation of the improved efficiency of all equipment across a site in response to the improvements in the power quality problems outlined above. It has been and continues to be a key technique for savings in energy consumption. Research in Taiwan suggested that, for an industrial supply, for voltage reduction upstream of the transformer, there is a 0.241% decrease of energy consumption when the voltage is decreased by 1%, and an increase of 0.297% when the voltage is increased by 1%. This assumed a mixture of loads including 7% fluorescent lighting, 0.5% incandescent lighting, 12.5% three phase air conditioners, 5% motors, 22.5% small 3-phase motors, 52.5% large 3-phase motors. for more details http://www.powerengineersco.com

Servo Voltage Stabilizers in Nigeria Under-voltage can cause damage to motors if it is excessive. A fixed mechanical load on a motor requires a certain amount of power to do the work. Since the amount of power the motor must draw is roughly the product of the voltage and the current, if the voltage decreases, the current (amps) must increase to do the same amount of work. If the current drawn exceeds the full-load value specified on the motor's nameplate, overheating and damage likely will occur over time. Under-voltage might cause production stoppages because the effects of low voltage are compounded during starting and acceleration. That is, under-voltage can affect the ability of a motor to overcome the inertia of its load at startup and slow its acceleration to full running speed. Typically the running speed stabilizes just slightly below normal but within ±10 percent of its nameplate value. However, so-called breakdown torque is reduced, and the motor is less capable of driving through a brief torque overload without stalling.
