Frequently asked questions.
Common questions about this service. Call our engineering team for anything else.
HARMONICS Why do textile mills require K-Factor rated transformers?
Textile spinning and weaving mills utilize large numbers of Variable Frequency Drives (VFDs) that inject severe harmonic currents. K-Factor rated transformers are specially engineered with transposed conductors and oversized neutrals to dissipate harmonic heat without derating.
SIZING What size transformer is needed for a 50,000-spindle spinning mill?
A 50,000-spindle modern spinning mill with blow room, carding, ring frames, and humidification plants typically requires between 3.5 MVA and 5.0 MVA total substation capacity.
VOLTAGE How does an On-Load Tap Changer (OLTC) benefit textile factories?
An On-Load Tap Changer automatically regulates secondary 415V voltage in real-time as utility 11kV grid voltage fluctuates, preventing expensive electronic motor drive trips without interrupting factory production.
