TRANSIENT OVERVOLTAGES An electrical network generally has a normal voltage: we also speak of nominal voltage. The network can be accidentally brought to a voltage higher than its nominal voltage: this is called overvoltage or surge voltage, if this one is very short. One of the possible causes of electrical or electronic equipment failure are the surge voltages . WHAT IS THE ORIGIN OF AN SURGE VOLAGE ? Surge voltages differ in amplitude, duration and frequency. While protection against power surges caused by lightning or switching will require the use of surge protective devices (SPD),...

Indirect effects of lightning Impact on overhead lines Such lines are very exposed and may be struck directly by lightning, which will first partially or completely destroy the cables, then cause high surge voltages that travel naturally along the conductors to lineconnected equipment. The extent of the damage depends on the distance between the strike and the equipment. Rise in ground potential The flow of lightning in the ground causes earth potential increases that vary according to the current intensity and the local earth impedance. In an installation that may be connected to several...

CONSEQUENCES OF SURGE VOLTAGES The lightning incident is relatively common. Statistically, the share of damage caused by lightning on computer equipment is far from negligible. The consequences of a disturbance are not always visible and immediate. The weakening of a component by an overvoltage can lead to a reduction in the lifetime of the equipment, or a ‘deferred’ failure. The user can therefore not make the link between the failure and the real cause. He will hasten to establish a bad diagnosis, therefore a bad treatment of the problem. Overvoltages have many types of effects on...

DIN RAIL AC POWER SURGE PROTECTORS CITEL AC power Surge Protective Devices (SPD) are designed to meet all your surge protection needs for any low voltage installation. These DIN rail mounted surge protectors are easy to install in any standardized distribution panel or control cabinets. The SPDs are equipped with a thermal disconnection device and provide real-time fault indicators thus allowing complete operational safety. DS and DAC surge protectors are available with several protection circuits to comply with even the most demanding installations and standards compliance requirements....

In order to improve the surge protection efficiency, CITEL has developed a patented technology which combines a high energy varistor (MOV) network and a specific gas tube (GSG). This specialized circuit incorporated in the «VG» Type “1+2+3” surge protectors (DAC1-13VG, DS250VG, DUT250VG) or Type “2+3” (DAC50VG) can achieve better perfor- mance of: • Protection level, • Life duration (due to suppression of leakage current), • Non-disturbing operation (no follow current) • TOV behavior. For instance, these features allow it to reach, even with a single stage of surge protection, the same...
