Without Surge Protective Device.ABB OVR® Surge Protective Device Transient overvoltage is a voltage peack of short duration (shorter than a millisecond) which amplitude can reach 20 times nominal voltage. 6 kV Surge Protective Device limits transient overvoltages and diverts surge currents to the ground. • when overvoltage reaches the Surge Protective Device. 4 ABB Lightning Protection Group . Surge Protective Devices act as an open circuit. 1. The whole surge current flows through the equipment and destroys it. This causes overvoltages on the electrical equipment directly via the earth terminals and induced via the underground supply cables. motors or inductances in general. the higher the overvoltages may be. Induced overvoltage Earthing Earth equipotentiality Strike on a lightning rod Switching operation on the power distribution system The switching of transformers. considerably raising the potential of the ground close to the building on which it is installed. MV disturbances transmitted to LV Parasitic interferences These are interferences with different amplitudes and frequencies that are injected into the electrical supply by the user himself or his environment. Significantly. • During a storm.Main causes for transient overvoltages Lightning strike • A lightning strike can have a destructive or disturbing effect on electrical installations situated up to several kilometers away from the actual point of the strike. cables can transmit the effect of a lightning strike to electrical equipment installed inside buildings. disconnection of circuit breakers or cut outs (i. be due to: • Arc furnaces • Welding equipment • Thyristors operation • Etc… • Contactors operation • Opening circuit breakers • Starting a motor Disturbances generated by the user These interferences have little energy but their short duration. their steep wave front and their peak value (that can reach several kilovolts) can have harmful effects on the proper functioning of sensitive equipment causing either disruption or complete destruction. sudden variation of load.e in the distribution circuits) lead to overvoltages that penetrate the user’s building. ABB Lightning Protection Group 5 . the closer the building is to a generating station or sub station. The parasites can. for example. It is also necessary to take into account mutual induction effects between the high voltage power line and aerial sections of the low voltages lines as well as direct contact between lines of different voltages caused by accidental breaking of cables. • A lightning protection device (such as a lightning rod or a Faraday cage) installed on a building to protect it against the risk of a direct strike (fire) can increase the risk of damage to electrical equipment connected to the main supply near or inside the building. Direct strike on overhead line Indirect lightning strike Surge current The lightning protection device diverts the high strike current to earth. to dissipate large amount of energy) and to limit the voltage to the lowest possible level. They also limit overvoltages to values compatible with the withstand of the equipment or devices connected. Parameters of the protection It can be easily understood from the above that the critical parameters of a surge protective device are its ability to divert high values of current to the ground (i. – A short waveshape (8/20 µs) which represents a damped indirect strike.

Need for multi-level protection Sometimes it is not possible to find a surge protective device which provides both the required current capability and protection level. In this case.

Pluggable Units The operation for changing failed cartridges is particulary safe: 1) the live contacts are inaccessible during the withdrawal phase thanks to a plastic side wall on the cartridge. installation time is consequently much shorter since it isn't necessary to disconnect and rewire the device (no tools needed). With pluggable products. Thanks to this cartridge system.Product overview Mono Block Units/Pluggable units Mono Block Units ABB proposes both mono block and pluggable products. 10 ABB Lightning Protection Group . 2) it’s impossible to swap a phase cartridge for a neutral cartridge thanks to an exclusive mechanical "arrow" system on the base. only the cartridge which has reached the end of service life needs to be changed. . installed to the left of the devices to be monitored and an receiver module R installed on the right..
