Options and accessories 

High voltage surge arresters

If the installation is likely to be subjected to overvoltage of any kind (atmospheric or switching), the transformer must be protected by phase-to-earth surge arresters, installed directly on the transformer’s HV connection terminals (either at the top or the bottom).
It is essential to install these surge arresters:

•  where the lightning impact level Nk is greater than 25. The risk of direct or induced atmospheric overvoltage is directly proportional to Nk

•  during occasional switching (less than 10 operations a year) of a transformer with a weak load, or during a magnetization phase. It is also highly recommended to install them: where the substation is supplied by a network including overhead parts, then a
  cable longer than 20 m (case of an overhead-underground network) Surge arresters can be installed in an IP 31 enclosure, or even on existing equipment, provided that insulation distances are adhered to.

Vibration damping
Roller anti-vibration pads
This accessory, placed under the rollers, avoids vibrations being transmitted from the transformer to its environment.
Damper unit
This device is installed instead of the roller and enables transmission of vibrations to the transformer environment to be attenuated.
