EN 60143-2:2013 includes the following significant technical changes with respect to EN 60143-2:1994: - updated with respect to new and revised component standards; - updates with
14、respect to technology changes. Outdated technologies have been removed, i.e. series capacitors with dual self-triggered gaps. New technologies have been added, i.e. current sensors instead of current transformers; - the testing of spark gaps has been updated to more clearly specify requirements and
15、testing procedures. A new bypass making current test replaces the old discharge current test; - Clause 5, Guide, has been expanded with more information about different damping circuits and series capacitor protections.

45、eries capacitor banks, with a size larger than 10 Mvar per phase. Protective equipment is defined as the main circuit apparatus and ancillary equipment, which are part of a series capacitor installation, but which are external to the capacitor part itself. The recommendations for the capacitor part
46、are given in IEC 60143-1:2004. The protective equipment is mentioned in Clause 3 and 10.6 of IEC 60143-1:2004. The protective equipment, treated in this standard, comprises the following items listed below: overvoltage protector, protective spark gap, varistor, bypass switch, disconnectors and earth
47、ing switches, discharge current-limiting and damping equipment, voltage transformer, current sensors, coupling capacitor, signal column, fibre optical platform links, relay protection, control equipment and platform-to-ground communication equipment. See Figure 1. Principles involved in the applicat
48、ion and operation of series capacitors are given in Clause 5. Examples of fault scenarios are given in Clause 5. Examples of protective schemes utilizing different overvoltage protectors are given in 4.1. BS EN 60143-2:201360143-2 IEC:2012 7 Key 1 assembly of capacitor units 2-7 main protective equi

Normally each module has its own bypass switch but a common bypass switch can be used for more than one module. See 10.2.3 of IEC 60143-1:
