Drive Isolation Transformer
GE Transformer’s dry-type drive isolation transformers are specifically engineered to support variable frequency drives (VFDs) and other non-linear load systems, delivering clean, stable, and balanced power in demanding industrial environments.
Designed to withstand the electrical and thermal stresses associated with VFD and SCR applications, our transformers effectively reduce harmonic distortion, minimize voltage disturbances, and protect both upstream and downstream equipment.
With optimized winding configurations, low leakage reactance, and high thermal capacity, GE Transformer solutions ensure reliable performance, improved power quality, and extended service life for motors, drives, and automation systems

FAQ
1. What is a drive isolation transformer?
A drive isolation transformer is designed to provide electrical isolation and stable power supply for variable frequency drives (VFDs) and other power electronic systems. It helps protect equipment, reduce electrical noise, and improve overall system performance.
2.Why are drive isolation transformers used with VFDs?
VFDs generate harmonics and electrical noise due to their switching operation. A drive isolation transformer helps mitigate these effects, protects upstream power systems, and ensures smoother and more reliable drive operation.
3. What is the difference between a drive isolation transformer and a general-purpose isolation transformer?
Drive isolation transformers are specifically designed to handle non-linear loads, high harmonic content, and dynamic operating conditions. General-purpose transformers are not optimized for these conditions and may experience overheating or reduced lifespan in VFD applications.
4.Can you customize voltage and specifications?
Yes, drive isolation transformers can be fully customized, including voltage levels, kVA ratings, impedance, insulation class, and enclosure type to meet specific project requirements.
5. What is K-factor and do I need it?
K-factor indicates the transformer’s ability to handle harmonic currents. For VFD and other non-linear loads, a higher K-factor (such as K13 or K20) is recommended to prevent overheating and ensure long-term reliability.
6.What standards do your transformers comply with?
Drive isolation transformers can be manufactured to meet UL, CSA, IEC, IEEE, and other relevant international standards depending on project requirements.
