The terms used in this standard shall comply with this standard, in addition, the rest shall comply with GB/T 2900.12-2008 and GB/T 2900.19-1994. 3.1 Metal-oxide surge arrester without gaps Arrester having non-linear metal-oxide resistors connected in series and/or in parallel without any integrated series or parallel spark gaps. 3.2 Non-linear metal-oxide resistor Part of the surge arrester which, by its non-linear voltage versus current characteristics, acts as a low resistance to overvoltages, thus limiting the voltage across the arrester terminals, and as a high resistance at normal power-frequency voltage (non-linear metal-oxide resistor, hereinafter referred to as "resistor"). 3.3 Internal grading system of an arrester Grading impedances, in particular grading capacitors connected in parallel to one single or to a group of non-linear metal-oxide resistors, to control the voltage distribution along the metal-oxide resistor stack. 3.4 Grading ring of an arrester Metal part, usually circular in shape, mounted to modify electrostatically the voltage distribution along the arrester. 3.5 Section of an arrester Complete, suitably assembled part of an arrester necessary to represent the behaviour of a complete arrester with respect to a particular test. A section of an arrester is not necessarily a unit of an arrester. 3.6 Unit of an arrester Completely housed part of an arrester which may be connected in series and/or in parallel with other units to construct an arrester of higher rated voltage and/or higher nominal discharge current rating. A unit of an arrester is not necessarily a section of an arrester. 3.7 Pressure-relief device of an arrester Means for relieving internal pressure in an arrester and preventing violent shattering of the housing following prolonged passage of fault current or internal flashover of the arrester. 3.8 Rated voltage of an arrester Ur Maximum permissible r.m.s. value of power-frequency voltage between its terminals at which it is designed to operate correctly under temporary overvoltage conditions as established in the operating duty tests (see 8.5). Note 1: The rated voltage is used as a reference parameter for the specification of operating characteristics. Note 2: The rated voltage as defined in this standard is the 10s power-frequency voltage used in the operating duty test after high-current or long-duration impulses. Tests used to establish the voltage rating in IEC 60099-1, as well as some national standards, involve the application of repetitive impulses at nominal current with power-frequency voltage applied. Attention is drawn to the fact that these two methods used to establish rating do not necessarily produce equivalent values (a resolution to this discrepancy is under consideration). 3.9 Continuous operating voltage of an arrester Uc Designated permissible r.m.s. value of power-frequency voltage that may be applied continuously between the arrester terminals in accordance with 8.5. 3.10 Rated frequency of an arrester Frequency of the power system on which the arrester is designed to be used. 3.11 Disruptive discharge Phenomenon associated with the failure of insulation under electric stress, which include a collapse of voltage and the passage of current. Note 1: The term applies to electrical breakdowns in solid, liquid and gaseous dielectric, and combinations of these. Note 2: A disruptive discharge in a solid dielectric produces permanent loss of electric strength. In a liquid or gaseous dielectric the loss may be only temporary. 3.12 Puncture; breakdown Disruptive discharge through a solid. 3.13 Flashover Disruptive discharge over a solid surface.
