Annex H
(normative)
Specific requirements for resistor fitted disconnector

in metal-enclosed gas insulated switchgear

H.1 General
H.1.1 Scope
This annex is applicable to resistor fitted disconnectors in metal-enclosed gas insulated
switchgear (GIS). The maximum VFTO (very fast transient overvoltage) in GIS systems with a
rated voltage of 800 kV and above may reach the insulation level of lightning impulse
withstand voltage in certain cases during switching of disconnectors. The purpose of fitting a
resistor is to mitigate the VFTO in such cases.
Three different types of resistor fitted disconnectors are given as examples in Figure H.1. The
resistor can be positioned in parallel or in series to the switching gap. In the arc-commutation
method the current is switched to the parallel resistor during an opening operation by
commutation of the arc from the main contact to the resistor contact.
NOTE Typically resistors of values 200 Ω to 1 000 Ω are used. The overvoltage damping factor depends on the
ratio of the resistance of the resistor and the system impedance.

H.1.2 Normative references
Subclause 1.2 of this standard is applicable.

H.2 Normal and special service conditions
Clause 2 of this standard is applicable.
H.3 Definitions
Clause 3 of this standard is applicable with the following modification:
Additional term and definition:
3.4.106
resistor fitted disconnector
disconnector fitted with resistor in series or in parallel to the switching contacts in order to
mitigate the VFTO during both opening and closing operation in metal-enclosed gas-insulated
switchgear

H.4 Ratings
Clause 4 of this standard is applicable.

H.5 Design and construction
Clause 5 of this standard is applicable with the following modification.

H.5.10 Nameplates
Addition:
The value of resistor, in Ohms, shall be given.
H.6 Type tests
Clause 6 of this standard is applicable with the following modifications.
Addition:
All type tests shall be carried out on the disconnector with the resistor fitted in the normal
position.
A measurement of ohmic value of the resistor shall be made before and after the following
type tests in order to ensure that the resistor integrity is still maintained:
– mechanical endurance test;
– bus-charging switching test;
– bus-transfer current switching test.
A visual inspection of the resistor shall be made after the type tests. No evidence of flashover
across the resistor or any mechanical damage shall be observed. It may be necessary to
disassemble the disconnector for the visual inspection.
The thermal capability of the resistor is verified during the
...
