Drive Isolation Transformers
Special design considerations must be made for the requirements of both adjustable
frequency and dc motor drive power isolation. Allowance for high surge, harmonic and
offset currents are taken into account in the design of Square D
transformers. Drive isolation transformers are not shielded isolation transformers, but act
to lessen transient generation into the supply power and act as a buffer for SCR current
surges.
