Effective protection against damaging Transient Voltages
Damages to home appliances, Electronics, PCB's and other electric equipment are a common feature found in developing countries.
In vast areas of Africa, lack of maintenance on Switch gears, Power Stations, HV Supply lines , faulty equipment, amongst others, can lead to problems affecting consumers.
In our research we conducted on domestic circuits we experienced not isolated cases of extreme Transient Voltage of up to 4000 Volts in a 3-4 m sec time frame.
These were found in residential areas, as well as remote country outposts.
In sequences of once per hour to 3-4 times in 24 hours, the fluctuating power has an absolute damaging effect on domestic, as well as industrial power appliances, ranging from simple incandescent light bulbs to heavy industrial equipment.
Three phase electric motors of all capacities are exceptionally sensitive, depending on Isolation class. Normally, in such areas a E class Insulation will not survive more than a few month.
To safeguard your equipment becomes a priority task. Avoiding the loophole of wrong protection mechanisms is a major factor in planning effective protection for home, or Industry.
Installing the right equipment is of essence.
Voltage Stabilizers are not suitable for short term power fluctuation control, and have a threshold of + - 25 %.
It is unsuitable for powerful currents which can impact at 100 000 A in some cases.
The equipments are tested according to DIN VDE 0100. Thus, one has a sufficient safety factor.
In cases of severe impacts, a pre-switched circuit breaker will provide additional protection, according to DIN VDE 0100 part 430 and DIN VDE 0185 part 1.
