Emmess'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 220 kV as per International Standards (IEC). Design Emmess'sOIP 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. Emmess'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. Design Highlights Thin Mild Steel Tank - leads to low Eddy Current in the CT tank and hence low heating even at higher currents. Thin Mild Steel Tank - Resilience effect - Absorbs mechanical shocks on primary terminals. Lumped Primary Winding with rectangular copper strips - Highest mechanical strength during Short Circuit conditions, thus gives high Dynamic Current withstand-ability. Specially designed rectangular copper lugs for CT primary winding terminations provide strong and reliable joints and no hot spots. Capacitive graded Insulation is provided in the secondary lead out bushing. This ensures uniform voltage distribution and partial discharge free performance ensuring longer life of the product. Crimped joints are provided on secondary leads. This averts loose connections possible in fastened joints. Cemented flanges are used on Porcelain Insulator. This results in uniform mechanical stress distribution on the elastomer gasket - joints and hence minimizes the prospects of any oil leakage. Process Highlights Major Paper insulation is dried in autoclaves, as per proven cycles under controlled vacuum and temperature. The EHV grade transformer oil is degassed and filtered until the desired properties are achieved. Each Instrument Transformer is pneumatically pressure tested at 1 kg/cm2 (gauge) at various assembly stages in order to assure the effectiveness of sealings provided. After oil flooding, each unit is hydraulically pressurized at 1 kg/cm2 (gauge) and maintained under pressure for 6 hours to ensure complete and homogeneous soaking of paper with oil and also checks effectiveness of sealings. Our products are adequately treated for corrosion resistance. Uniform Insulation thickness with capacitive graded Condenser Bushing is used in all Current and Voltage transformers from 12 kV up to 220 kV Class. Tests And Performance All Product designs have been validated by type-tests as per applicable IEC Standards.  

Constant Voltage Transformers are used to regulate output voltages for applications that have varying input voltages. They provide an elegant approach of voltage regulation when used with a rectifier conversion circuit. Our innovative approach is by partnering the CVT with an auxillary resonant capacitor winding. This unique technology offers reliable performance and cost advantages over other methods of voltage regulation.   Features Controlled output Modern construction High correction rate High/low cutoff option

Elite CVT are rugged in design with proven track record for several decades. ELITE constant voltage transformer CVT which are Ferro Resonant types. It is also known as ferro resonant transformers and it gives constant Output even in heavy Input Fluctuations. All problems related to voltage variations / fluctuation is effectively handled because of this principle and gives constant voltage output of ± 1%. The output of the CVT is taken from the saturated secondary section of the transformer which has an energy reserve close to 5 -10 ms at full load and continues to deliver power from its own energy reserve.   In our Constant Voltage Transformers – CVT, the AC mains power the input winding, which is widely separated physically from the isolated output winding. The input winding normally runs at very moderate Flux linkage levels. The output winding exhibits an intrinsic energy characteristic and this energy storage operate in conjunction with mains capacitor to produce self-generated AC flux Field which is indirectly extracted from the Input Winding.   Output is accuracy with built in Stabilizer function • ZERO electrical noise, as no moving parts or semi-conductors are used. • 100 times faster than servo stabilizer. • Built-in Spike, Surge & RFI Suppression • Complete Isolation • Built-in Short Circuit & Overload Protection • Can work at very low voltages on partial load. • Can be used for solar powered inverter. • Easy paralleling. • Indestructible. • Efficiency: Better than 87% at rated load • Correction Time: Less than 37 Milliseconds • Output wave form: Sine wave, THD less than 4%
