Voltage fluctuations have been common and quite high in India. They harm our electrical appliances like televisions, refrigerators and air conditioners, often leaving them in a permanently damaged condition. N-Guard Company decided to manufacture stabilisers 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 stabilizers of varying voltages from 90 V -260 V for meeting the requirements of voltage fluctuations 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 stabilisers but the product differed from region to region.
