The issue is one of those problems more popular in third world countries because power systems are outdated, dilapidated, superannuated, antiquated and crusted. Thus, during heavy thunderstorms and gust, there is a high likelihood of extremely high short-circuit currents which can damage our many unprotected transformers, feeders and other plants. Also, it is possible to get clashing conductors, conductors snapping and broken wires which can electrocute humans walking along the roads. Rather than invest in proper network protection and earthing, DisCos switch off supplies. This is unintelligible and counter-productive.
During a heavy downpour, rainwater reduces the insulation capacity of electrical gadgets installed on power transmission and distribution networks. This leads to dangerously high short-circuit currents flowing in our extremely weak power network. Also, line to ground faults can occur as a result of the failure of insulation just as occurs with the direct contact of line conductors with the ground. Short-circuits blow fuses, and damage the myriads of unprotected equipment on our power network.

Besides, numerous road accidents happen during rainfall because vehicles and animals ramp into electric posts causing power interruption. Rather than invest in auto-reclosing and automated systems which will put circuits back in service automatically after transient faults, DisCos prefer to switch off supplies to avoid the real work of replacing damaged equipment due to faults that may occur during rainfall as this costs time and money.
Another occurrence during thunderstorm that is associated with rainfall is lightning. When lightning strikes power lines and towers, the resulting high voltage causes power surges which can damage our unprotected critical switching and voltage regulation components at power distribution and transmission substations resulting in blackouts.

In addition, due to our not operating with industry standards of electricity design, planning, control, protection, maintenace, and vegetation management, severe wind gusts experienced during rainfall cause branches, and at times, entire trees, to fall on power lines, interrupting power supplies.
Truth be told, some of the above causes of power failure can lead to the switching off of supplies even in advanced countries but this will be for situations when the level of severity is clearly beyond their control and not because of lack of investment in the network as it is in our case.
