Recommended Protection to Potential Danger
Electrical surges are high frequency current events that present potential danger to todays sophisticated electronic devices. Electrical surges can occur for many reasons and at almost any time, but the most common causes are lightning strikes, the switching of inductive loads, power grid disturbances, general fault or arcing conditions. In the case of a direct lightning strike the damage caused by surge current is clearly felt and often visible, however many other electrical surge events can go by unnoticed. The consequences of such ‘quiet’ disturbances are not always inconsequential.
Surge currents can cause loss of data transmission, switch tripping, disturbance of machine control systems and a slow but noticeable degradation of circuit elements. In addition, a surge can be an indicator of a short circuit which causes currents of power to travel along unintended paths with little or no electrical impedance, for example after a blackout or wiring insulation damage.
Raycap’s ProGRID surge and lightning counter solutions have different capabilities that can sense, record and transmit the occurrence of otherwise undetectable surge currents, enabling users to take preventive measures and plan appropriate maintenance.
