Three Phase Distribution Transformers (upto 2000KVA) (CRGO Silicon Steel) SLVI’s Three Phase Distribution Transformers utilize the most advanced and versatile design, delivering excellent performance characteristics. Technical Specification:  Applicable Standards: IS, IEC, ANSI, JIS, BS etc, Cooling : ONAN, OA, Insulating Fluid : Mineral Oil to specification, Frequency:50 Hz, 60 Hz, Polarity : As specified, Primary voltage : Upto 33 kV, Secondary Voltage:415, 433 V (Other Voltages as required) , Winding material : Copper / Aluminum, Taping range:± 5% in steps of 2.5% (Other tapings as required). Impedance: in Line with applicable standards. Completely Self-Protected Transformers (utpo 315KVA) (CRGO Silicon Steel) SLVI’s Self Protected Transformers (CSP) offer a complete and safe solution against lightning, switch surges and server secondary overloads. Benefits: Higher Transformer Availability:  Available for a longer duration than conventional transformers. Internal breaker (Type CLR) is tripped by a standard Bi-Metallic thermal trip element, which integrates oil temperature and secondary current flow, allowing the transformer to continue to operate even under overload conditions, until the oil temperature makes coil damage imminent. Improvised CQR Type breakers can also be provided which are furnished with instantaneous magnetic trip element in addition to the Bi-Metallic thermal trip element. More Reliable Service:  CSP Transformers efficiently and effectively disconnect the load from the transformer under overload conditions. Moreover CSP components help in identifying locations where improvements in load management may be necessary. Technical Specification:  Applicable Standards: IS, IEC, ANSI, JIS, BS etc, Cooling : ONAN, OA, Insulating Fluid : Mineral Oil to specification, Frequency:50 Hz, 60 Hz, Polarity : As specified, Primary voltage : Upto 33 kV, Secondary Voltage:415, 433 V (Other Voltages as required) , Winding material : Copper / Aluminum, Taping range:± 5% in steps of 2.5% (Other tapings as required). Impedance: in Line with applicable standards.
