Technological Details Technical Terms Active Parts Active parts are conductors and conductive parts of equipment that are alive under normal operational conditions. Aging Aging is the alteration of the original conductivity. It is caused by disturbance pulses, normal operation or unfavourable environmental conditions. Approach (today: Separation Distance) An approach is a too narrow distance between the lightning protection installation and conductive installations or electrical installations with a risk of a flashover or breakdown at lightning strikes. Arc Voltages U bo The arc voltage is the instantaneous value of the voltage over a discharge path during an arc discharge process. Arresters Equipment that in general consists of voltage-controlled resistors and/or spark gaps. Both items can be used separately or connected in series or in parallel. Arresters protect other electrical equipment or installations against unacceptable high surge voltages. Asymmetrical Interference “Asymmetrical” means that the interference source or drain is related to the ground. It exists a capacitive or galvanic connection to the protective conductor. Asymmetrical Voltage, Common-Mode Voltage Average voltage between every conductor and a specified reference point, usually reference earth or ground. Burst A burst consists of repeatedly occurring pulses within a certain time period. Combined Arrester The combined arrester is a surge-voltage protection device consisting of lightning current arrester and surge arrester. Combined Impulse A combined impulse is generated by a combination wave generator which generates a no-load impulse voltage (1.2/50), respectively, a short-circuit impulse current (8/20). The voltage, the amplitude of the current and the waveforms are determined by the generator and the impedance of the SPD. The ratio of the peak values of the noload voltage and the short-circuit current is 2 Ω. This value is called the fictitious impedance Z f . The short-circuit current is referred to as I cs . U oc is the no-load voltage of the generator. Critical Discharge Current i SG The critical discharge current is a current pulse of the waveform 8/20 μs which just about triggers the disconnection device and which does not yet lead to a mechanical damage of the arrester. Direct or Close-up Strikes Direct and close-up strikes cause surge voltages with an energy content that contains a considerable part of the total energy of a lightning discharge. Disconnection Device If an arrester fails to operate, the disconnection device separates it from the power grid to avoid a fire hazard and to report the defective arrester. Note: It is not the task of the disconnection device to ensure the protective measure „Protection at indirect contact“. Disturbance Voltage, symmetrical The symmetrical disturbance voltage is a disturbance voltage between two wires of a conductor (e.g. at a double-circuit line) or between the terminals of an electrical installation for such a line. Double-port SPD A double-port SPD has separate input and output terminals with a series impedance between them. Earth Earth signifies the ground or the soil. Earthing (noun) Earthing refers to the total of all means and measures for earthing. Earthing (verb) To earth means to connect a conductive part, e.g. the lightning protection installation, via an earth-termination system to the earth. Earthing Conductor The earthing conductor connects the installation which has to be earthed with the earthing electrode, as far as the earthing conductor runs above soil or insulated in the soil. Earthing Electrode An earthing electrode is a conductor buried into the ground with an electrically conductive connection to the earth. Parts of connectors that run to the earthing electrode which are lying non-insulated in the ground are part of the earthing electrode as well. Electromagnetic Compatibility (EMC) The electromagnetic compatibility of a device or a system is its capability of a satisfactory operation in its electromagnetic environment, without causing unacceptable electromagnetic disturbances to other installations in this environment.
