OIP Insulated Outdoor Instrument Transformers

Current Transformer

Gemini’s range of OIP Insulated Instrument Transformers use Oil Impregnated Paper  Insulation and are designed for serving in Outdoor applications,  with several unique features with one aim – TOTAL RELIABILITY. Our present range of OIP Current Transformers  include CTs from 12 kV to 145 kV as per International Standards (IEC).

Gemini’s OIP insulated outdoor products are subjected to extreme climatic conditions at Customer Sites and hence Quality and Reliability have been built into the Product, right from the design stage and are followed up through established manufacturing processes, rigorous In-process Quality checks and the designs validated by exhaustive type testing and satisfactory field performance.

Gemini’s design philosophy aims at the following  aspects :

• True Hermetic Sealing ensures that the OIP Insulation retains the original properties even after several years of field operations;
• Our products are well engineered, our processes are well established. These factors ensure high reliability of our products whilst in service.
• Our products are truly maintenance-free; hence, only periodical cleaning of the products is required.
• Our products are designed to be user-friendly - right from unpacking, handling, erection, testing, commissioning and day to day operations in the field.
•  Safety has been built into our products.  Even in the unlikely event of an internal failure, the Instrument Transformer DOES NOT SHATTER or explode. A corrugated Stainless Steel Diaphragm has been provided, which, besides lending compensating volume for oil expansions during normal operations, acts as a proven pressure relief device, by peeling off from the tank from the weld    and  thus  averts any explosion of the porcelain insulator.
