AC Resonant Test Systems with Variable Inductance

Resonant test system with variable frequency and variable inductance has special application in testing of instrument transformer (voltage transformers). Frequency is changed from 50 Hz to 100 or 150 Hz so that the core of voltage transformer do not saturate and then by varying the inductance resonance in formed to produce high voltage for testing.

Main equipment:

• Double Shielded Isolation Transformer
• Static Frequency converter
• Exciter Transformer
• HV Variable Reactor
• Laptop Based Controller
• HV Filter cum coupling capacitor
•
