Preventing power surges
Power surge damage can cause havoc with your electrical appliances in your home, particularly fridges, TVs and computers. Unfortunately your driveway and garage door gate motor is not spared. Your gate/door motor is particularly vulnerable due to the nature of it being a motor, switching on and off when used.
A power surge explained:
A power surge occurs when the electricity flow is interrupted and then started again, at a higher voltage. A power surge can also happen when something sends electricity flowing back into the system, creating higher voltage such as power surge energy. All electrical appliances are designed for very specific voltage, to make them functional. Any increase in voltage potentially puts this appliance at risk of being damaged.
Most power surges happen within the house’s electrical wiring system due to “electronic rust”. Small voltage surges over an extended period of time are capable of causing damage due to the build up of “electronic rust”. Electronic rust occurs when the electrical wires heat up and cool down over a period of time.
Yet we are particularly vulnerable to another form of power surge living in Johannesburg - lightning strikes. A lightening strike can shed thousands of volts, hitting the gate motor’s circuit board directly or power cables in the vicinity. This causes your motor charger or circuit board to literally melt, resulting in repair work or replacement.

So when you do see that ominous storm brewing, it is wise to unplug your sensitive appliances in your home such as computers, sound systems and TVs to avoid lightening power surges from damaging them.
Cable theft, which has become rife in Johannesburg in the last few years, is the third cause of power surges in your home. This sudden interruption from the power lines potentially causes extensive damage to your house appliances.
The fourth cause of a power surge is when power is re-instated after a shut down, as we experienced during load shedding in Gauteng. The power grid is flooded with a sudden increase in voltage. The inrush of electrical current puts electrical appliances at risk.
Preventing power surges damaging your gate/door motor, it is advisable that you have some form of surge protection, which Gate Repair Services do have in the motors that they install. Gate Repair Services also earth the motors on installation which reduces the risks of damage to the motor if affected by a surge. Unfortunately nothing stops heavy lightening! If you live in an area in Gauteng that experiences heavy lightening, further surge protection for your house is recommended.
