There are many possible reasons for this issue. Transformers that are dieing, Connections that are lose or wires breaking are three possible issues.
This can become a very serious situation. Contact your electric supplier right away.

Why capacitor oppose change in voltage and allows current to flow?
Because that is what a capacitor does, resist a change in voltage. It holds a certain amount of energy per charge (voltage), and to change that voltage requires current proportionally to the capacitance.
What is impulse votage?
Sudden rise in Voltage is called Impulse voltage.
What is the effect if there is a sudden flow of electric current?
electric shock
What is the function of shunt reator?
it is electrical device connected with high voltage current grids in order to protect the system from sudden drop or sudden change is voltage.
Which condition refers to a sudden increase in voltage?
That would be 'spiking'
Which condition refers to a sudden and dramatic increase in voltage which usually caused by lightning?
Surge voltage, voltage step, voltage spike
What is surge voltage?
Surge voltage means sudden big voltage. Surge voltage is of two types lightening surge and switching surge or in electrical engineering, a voltage rise that endangers the insulation of electric equipment. A correct calculation of voltage surges is of great economic and practical importance in the selection of insulation and of measures for power supply system protection, particularly for voltages above 10kilo-volts(kV). There are two types of voltage surges lightning surges and system generated surges.
What is the uses of bank?
In high voltage situations, a capacitor bank stores a charge of electric, similar to a battery, so that when a sudden large draw is put on the line, thus causing the voltage to drop, it will do a temporary release of stored energy into that line causing the sustained energy level to be more stabilized.
What are common causes of transient voltage?
Sudden starting of large inductive loads..
Why electric field lines cannot have sudden brakes in between them?
electric field lines represents electric field at that point but if it has break somewhere then it signifies the absence of electric field and it is not possible.....
What alternative devices can you use if there is a sudden breakdown in electric supply?
A bad boy
What is spike current?
A spike is a sudden rise in current that then goes back to normal. Usually caused by a sudden increase in voltage that could be caused by a lightening strike, for example.
