Skid-mounted VSD

This type of VSD is a fully integrated Skid Base, including the following components on one skid:

  • step-down transformer: 0.4 up to 33 input kV
  • VSD in an air-conditioned compartment
  • step-up transformer: 1...4 kV

Skid has IP55 type of protection against dust, insects,water sprays and designed to fit into a 40 ft High Cube Container or 40 ft Open Top container. The most important features of Novomet Skid-mounted VSD is it’s self-contained design and 12-pulse input voltage rectifier scheme.

A 12 pulse drive has two diode rectification bridges (12 rectifiers) and a 6 phase input. Total harmonic distortion (THD) by current of a 12 pulse drive is usually significantly less than that of 6 pulse system.
