Engineering & Sizing FAQs

Frequently Asked Technical Questions

Key considerations for industrial electrical engineers, facility managers, and procurement directors.

Why is an Ultra Isolation Transformer needed if a facility already has a voltage stabilizer?
A voltage stabilizer corrects amplitude fluctuations (volts), but does not filter high-frequency common-mode noise, ground loops, or transient spikes. An Ultra Isolation Transformer provides complete galvanic decoupling with electrostatic shielding, stopping ground-borne noise and spikes that damage microprocessors in CNCs and diagnostic machines.
What does K-Factor mean in industrial transformers?
K-Factor indicates a transformer’s ability to handle thermal eddy current losses caused by harmonic load currents from non-linear loads (such as variable frequency drives, computers, and welders). Standard transformers overheat and degrade under harmonics; Airkom K-rated transformers use oversized neutrals and transposed copper conductors to run cool.
What cooling configurations are available for Airkom power transformers?
We manufacture naturally air-cooled (AN), forced air-cooled (AF), and oil-immersed naturally cooled (ONAN) transformers in ratings from 1 kVA up to 2,500 kVA, compliant with IS 2026, IS 11171, and IEC standards.
Can Airkom build step-up and step-down transformers for imported machinery?
Yes. We frequently supply custom step-down (e.g. 415V to 208V/220V/380V/480V) and step-up transformers for imported CNC machining centers, Japanese SMT lines, European packaging equipment, and US-spec industrial automation.
