VSD Step Down transformers

Step down transformers are used with ESP Frequency Drives of 6, 12, 18 and 24 pulse secondary windings. Transformers designed to work with 12, 18 and 24-pulse secondary windings. Transformers designed to work with those drive are “K-rated”, which means that they have been designed taking into consideration the harmonic loads in order to keep losses low. They help reducing the problems caused by harmonic currents including overheating cables, especially the neutral conductor, overheating and vibration in induction motors, etc. They are supplied with a full complement of gauges for user monitoring and performance, including oil level, temperature and vacuum pressure gauges. They can fit bushings on the cover or in single or double enclosures made of porcelain/ceramic or elbow connectable type.

1- Step Down 6-Pulse VSD application
Step down 6-pulse transformers are designed to operate standard three phase systems



2- Step Down 12, 18 and 24 pulse VSD application
Step doen 12,18 or 24-pulse transformers are designed to operate with 12,18 or 24-pulse drives when reduction of harmonic currents are required.
