LIT INDUSTRIES is a leading manufacturer of high-performance Inverter Duty Transformers (IDT) designed specifically for large-scale solar PV plants and wind energy projects. As a trusted partner for EPC contractors and solar power developers across India, we engineer our transformers to withstand the unique harmonics and pulsed wave requirements of modern solar inverters. Our Inverter Duty Transformers are built to ensure seamless power integration from the DC-AC conversion stage to the utility grid, minimizing losses and maximizing ROI for your renewable energy assets. Key Technical Features: Multiple Windings: Designed with split secondary windings to connect multiple inverters to a single transformer, reducing footprint and installation costs. Harmonic Suppression: Specially reinforced insulation and electrostatic shielding to handle high-frequency harmonics generated by solar inverters. High Efficiency: Low-loss core design (CRGO) to meet Star Rating standards and ensure maximum energy yield. Robust Thermal Management: Optimized cooling systems (ONAN/ONAF) to handle peak solar generation hours without overheating. Grid Compliance: Fully compliant with IS and IEC standards, ensuring smooth approval for government and private solar tenders. Why Choose LIT INDUSTRIES for Your Solar Project? We understand the tight timelines of EPC projects. Whether it’s a 1 MW rooftop installation or a multi-megawatt solar park, our Inverter Duty Transformers provide the reliability required for 25-year plant lifecycles. Customization: Tailored voltage ratios (e.g., 11kV/800V, 33kV/600V) to match your specific inverter brand. Proven Track Record: Supplying robust power solutions from our Vadodara-based manufacturing facility to clients nationwide. Testing Excellence: Every unit undergoes rigorous factory acceptance tests (FAT) to ensure zero-defect performance on-site. Applications: Grid-tie Solar Power Plants (Utility-scale) Commercial & Industrial (C&I) Solar Installations Wind Energy Power Conversion Battery Energy Storage Systems (BESS)

Present development and production of power transformers with lower losses in addition to replacement of outdated transformers assume regular measurement of losses in both load and no-load regime. These measurements are very demanding especially in the case of on-situ measurements. The complexity of the measurements grows with the size of transformer. This paper presents one typical test of losses measuring in load and no-load regime of power transformer with nominal power of 40 MVA in HPP Perucica.
