Voltage Variation is a common phenomenon across the world, esp. in developing and under-developed nations. Voltage variation manifests in many different ways:
Low Voltage or Sags: Sags might be due to undersized distribution lines, connection of large loads to the network, ground faults, and units located towards end of a long supply lines, etc.
High Voltage or Surges: Surges might be generated by disconnection of large loads, increase voltage at generating plant, atmospheric events, units located close to start of a supply line, etc.
Unbalanced Voltage: Phase to phase unbalancing in voltage is generally observed where multiple consumers draw power from a common distribution line or in remote locations far from power grid.
The duration of the above phenomena depends on the cause and is not predictable easily. Generally, voltage is low during the daytime & high during the night hours. Moreover, on holidays, peak hours, rainy days and when the commercial / agricultural load is switched off, the voltage rises quite sharply.
Voltage variations can play havoc with electrical & electronic systems & even bring the whole plant to a grinding halt. Even though you may currently not be experiencing the negative effect of voltage variations, it doesn’t imply that your unit is free from that problem!!! Your supply may be full of variations, but none has yet been severe enough to trigger a shutdown. Your electrical gadgets may be exposed to a significant risk, where a small increase in severity of the voltage variations could cause crippling losses.
