Inverter Duty Transformer – IDT
Inverter Duty Transformers are specially engineered to operate with power electronic equipment such as inverters, where high-frequency harmonics and rapid voltage fluctuations are common. These transformers are widely used in renewable energy systems like solar and wind power plants, ensuring smooth power conversion and grid integration. With ratings up to 20 MVA and voltage class up to 33 kV, Inverter Duty Transformers are designed to handle non-linear loads and dynamic operating conditions.
At Telawne, we manufacture high-performance IDTs built for durability, thermal stability, and harmonic resilience, meeting the stringent requirements of modern energy systems.
Assured Features
- The Highest dielectric insulation property to withstand Lightning Impulse.
- Mechanical design to withstand short-circuit forces arising during faults.
- Optimum oven heating under vacuum is required to achieve the desired compression height and maximum insulation resistance (IR) to windings.
- Adequate ducts between layers, coils, and discs for maximum oil flow and reduced hot spot temperature.
- Step-lap designed CRGO laminations for lower losses and excitation current.
- Pre-compressed Insulation material for minimal moisture absorption.
