PROTECTING YOUR EQUIPMENT
Momentary interruptions caused by surges and other similar electrical disturbances cannot be prevented completely. This is because the overhead and underground lines that deliver electricity are exposed to hazards such as:
- vehicle accidents which can damage poles
- trees which can fall on lines
- wind, heavy rains or lightening strikes that can cause lines to come in contact, and
- facilities that improperly operate or attach loads to the electrical system.
It is therefore your responsibility to protect your valuable electrical equipment from possible damage.
Your computers, motors and other commercial equipment require smooth, uninterrupted flow of electricity for proper operation. Even the slightest electric disturbance can lead to bothersome computer reboots, blinking on-clock displays, and even permanent damage. And significant power dips, surges or outages can damage expensive electrical equipment such as photocopiers, air conditioners and motors.
To mitigate against equipment damage, we recommend regular inspection of the wiring and grounding on your property to ensure that the requisite standards of safety and service are maintained. Surge protection devices should also be used to protect your electronic equipment from voltage spikes, even though full protection is not guaranteed. Surge protectors can be installed at the main electrical panel and/or at individual equipment e.g. photocopiers. Computers, which cannot withstand even the shortest outage, can be connected to an Uninterruptible Power Supply (UPS). Additionally, large motor loads can be protected by phase monitors against loss of phase, phase imbalance etc. It is however recommended that you consult a qualified electrical contractor before implementing your protection scheme.
WHAT CAUSES POWER SURGES?
Surges can be caused by lightning (which create high voltage in electrical circuits), overloading, or the normal operation of switches and breakers within the premises. Always unplug electrical equipment during a lightning storm, and never overload electrical circuits.
