Repairs replacements to damaged 100 KVA 11 KV HT LT Distribution transformer and 63kVA at Sheikhpora Well no 07 Sandipora and Gazergund

Amount

Repairs to the 100 KVA HT/LT transformer pertaining to WSS Sheikhpora Well no 07, Sandipora by way of:- (1)Disconnecting the transformer from HT/LT circuit. (2)Un-mounting the various connections from its platform and loading, it in a private load carrier for shifting to workshop. (3)Opening of the transformer involving removing of top cover and lifting of the core, checking HT/LT coils, Core thoroughly after draining of the transformer oil by suitable means. (4)Extracting the silicon core, so as to have access for removal of the damaged HT/LT Coils. Dismantling the core strips, cleaning and heating the core strips etc through suitable means to remove moisture completely. (5) Fabrication, providing, rewinding and fitting of new HT coils in place of damaged ones and re-assembling the transformer by way of re-conditioning of the LT Coils. The Bakelite pieces, lamination paper, lathoride paper cork sheet gaskets and other sundry items required during reassembling to be provided and fitted by the contracting agency. (6)Filtering the transformer oil to remove moisture, impurities completely from oil and then back filling it into the transformer. (7)Drying out of the transformer core-winding assembly in oven for moisture removal and complete bonding between winding and insulation till peak value of insulation resistance is achieved. (8)Open circuit, short circuit and step up testing of assembled transformer. (9) Loading of transformer into a private load carrier by suitable means shifting it back to the site and installing the same. (10) Reconnecting the transformer in the circuit and then testing it on no load and full load. Old scrap shall be retained by the contracting agency. All Tools, tackles and labours (skilled/unskilled) required for the job are to be arranged and brought to site by the contracting agency.
