Motors & Transformers switched by Vacuum Circuit Breakers & Contacters

Metrosil Surge Diverters Type VSD have been designed to provide effective protection against voltage surges which may sometimes result from the operation of power distribution switchgear.

The range of diverters is suitable for systems having working voltages from 3.3kV to 11kV rms. The diverters have been specially developed to provide optimum protection under severe switching surge conditions. 

VSD surge diverters have been designed for use on power distribution applications where switching is infrequent, but stored energy levels are high. 

VSDs are particularly suited for protecting all types of transformers, generators, motors and any device/load where impulse voltage withstand level is low or not known.

 

Metrosil MIMOX type SVL has been developed specifically for switching applications where the surge to be suppressed may have a fast rise time, but low energy content.

Their rated voltages are from 1.2 kV to 15.5 kV. Type SVL Diverters are constructed from metal oxide varistors, which are highly non-linear and thus offer excellent protection levels. 

This type of diverter is recommended for use with any device (transformer, motor) where the withstand impulse voltage is low and high-energy absorption is not required. They are particularly useful for loads, which are switched with vacuum contactors.
