Why does Schneider Electric recommend Drive Isolation Transformers for use with Variable Frequency Drives?

Issue:
Drive Isolation Transformers for VFD's

Product Line:
LV Transformers

Environment:
Applies to Low Voltage Transformers by SquareD by Schneider Electric

Cause:
Variable Speed/Frequency Drives can be unusually difficult loads for standard Transformers

Resolution:
Variable Frequency Drives make special system design characteristics an important consideration in selecting Transformers. SquareD/Schneider Electric`s Drive Isolation Transformers (HDIT's) allow for high inrush current, offset current and harmonics and help to lessen transient generation into the supply power and act as a buffer for SCR surges.
