3 Terms and Definitions
For the purposes of this standard, the following terms and definitions apply.
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.
