Most equipment requires a constant power, i.e. constant voltage, current and frequency. Voltage dips occur on the system continuously and, depending on the susceptibility of your systems and equipment, will affect you to a different degree. Unfortunately they can occur many hundreds and even thousands of times a year, and the causes are usually unavoidable.
The main problem with voltage disturbances is that they vary in magnitude, duration and the phases that they affect. When equipment experiences a voltage depression this can result in loss of tension (quality issue), corruption of data, machines stalling, production stopping or fall out of sequence and, in the worst cases, damage to equipment. All of these issues can result in lost production, clean up costs and spoilt products and downtime. Therefore the affect of voltage dips tends to be very costly to businesses and disruptive to most consumers, making voltage disturbances one of the most common and notorious power quality phenomenon.

Voltage dips occurs when a highly inductive load is started or running along a common point of coupling where other loads are connected. This affects the voltage requirement of adjacent loads which sometimes results to annoying lamp flicker. One remedy to reduce voltage dips is to connect this highly inductive load to a higher point of coupling. (busbar with higher voltage level through a transformer).
