The three-phase load break switch is installed on one sectional galvanized steel base, joint together with one drive axis to ensure closing and opening of three poles synchronously. The switch opens or closes under rated load current, without requiring any secondary protection device.
Load break switch switches the current by mechanically moving their contacts with an appropriate speed in order to make (close) or break (open) the current. It is exposed to mechanical, thermal and dielectric stresses during switching operation. Hence, for investigating and in detail exploring the interrupting capabilities of load break switch, they need to undergo various test duties according to IEC . The essential parameters that are taken into consideration for analysing the behaviour of the load break switch during breaking tests are the current levels and the transient recovery voltage (TRV).
