AS/NZS 60265.1:2001 pdf download.High-voltage switches Part 1: Switches for rated voltages above 1 kV and less than 52 kV.

3.4.105.1

single capacitor bank switch

special purpose switch intended for switching of a single capacitor bank with charging currents up to its rated single capacitor bank breaking current

3.4.105.2

back-to-back capacitor bank switch

special purpose switch intended for breaking capacitor bank charging currents with one or more capacitor banks connected to the

supply side of the switch up to its rated back-to-back capacitor bank breaking current. The switch shall be capable of making the

associated inrush current up to its rated capacitor bank inrush making current.

3.4.105.3

motor switch

special purpose switch intended for switching of motors under steady-state and stalled conditions

3.4.105.4

parallel power transformer closed-loop switch

special purpose switch intended for switching a closed-loop circuit consisting of large power transformers in parallel. The switch is typically applied as a medium voltage tie switch on the transformer secondary circuit such that the breaking current is high

and the transient recovery voltage (TRV) conditions are severe.

breaking capacity

[1EV 441-17-08)

3.7.102

mainly active load-breaking capacity

breaking capacity when opening a mainly active load circuit, the power factor of which is at least 0,75. in which the load can be

represented by resistors and reactors in parallel.
