Power Protection for Personal Computer Equipment

Voltage in Khartoum is 220V AC 50 cycle, but the supply is extremely irregular.  Power fluctuates in two directions: up and down.
 
When electrical power goes down, it can merely dip slightly or, more common, go out suddenly and completely.  Protection against outages is provided by an UPS (Uninterrupted Power Supply) which are available commercially.
 
When electrical power goes up (spikes or surges), the UPS does not provide protection.  In such a case, a surge protection is needed.  Once again, these are available commercially.  No particular make or model is recommended, but the more expensive ones have the protection that is needed here since surges are more extreme than is usual in the West.
 
Residences are supplied with three step-down transformers.  If this number is not sufficient for your appliances, employees are expected to purchase additional transformers.  It is best to purchase such items outside of Khartoum because quality and availability of these items is spotty.
