Voltage fluctuations have been common and quite high in India. They harm our electrical appliances like television, refrigerators and air conditioners, often leaving them in a permanently damaged condition. N-Guard Company decided to manufacture stabilizers for North India where the voltage fluctuation ranges from 220V to 230V. Once the demand for North India was taken care of, they decided to launch stabilisers of varying voltage from 90 V−260V for meeting the requirement of voltage fluctuation in other regions of India also. Three engineers were appointed for South, West and East regions of India, as the voltage was different in all the three regions. Though all the engineers were appointed to manufacture stabilizers but the product differed from region to region.
