A well maintained equipment not only serves its purpose efficiently, economically and quickly but also exceeds its expected lifetime. After formation of PTCUL as a State transmission utility to maintain, operate and run the State Grid of Uttarakhand as per Grid Code as well standard practices and procedures, the need of an O&M manual became essential. This Manual has been prepared for existing transmission network of PTCULi.e. decade old Transmission lines, substations in plane and hilly terrain as well as new lines and substations added to the system to maintain balance of Load and Generation etc. There are two type of maintenance:  \ni) Preventive Maintenance  \nii) Break down Maintenance  \nPreventive maintenance is a routine and regular maintenance to prevent future breakdown.  \nWhile framing this O&M manual for Substation and lines an attempt has been made to formulate proper guidelines, directions and instructions with suitable standard data and ratings, which will be helpful to field officers and staff for timely maintenance.  \nThis O&M manual consists of two parts:-  \nPart – I deals with Preventative Maintenance of Substation Equipments and Protective Switchgears.  \nPart – II deals with Preventative Maintenance of Transmission Lines.  \n􀁸 The emphasis has been given to include the operation and maintenance procedures of new and modern technology for substation equipments and protective relays.  \n􀁸 The efforts have also been made that this manual shall be compatible with new state Grid code of Uttarakhand and also with relevant IS/IEC standards. A special topic of GIS systems being used for substations has also been incorporated.  \n􀁸 This manual covers preventive and normal breakdown maintenance and does not include the major repair works. The effort has been made to make the manual comprehensive and authentic. However suggestion for further improvement are always welcome.  \nRegulatory and statutory guidelines for carrying out Operation & Maintenance of transmission System.  \n(A) While carrying out operation & maintenance of transmission network, the regulations notified by Uttarakhand Electricity Regulatory Commission are also to be complied with. Terms & conditions for determination of Transmission tariff Regulation 2004 dated 25.08.2004 of UERC specifics regulations in respect of Transmission system availability and incentives, the relevant portions are given below:-  \n13. Target Availability for recovery of full transmission charges  \n(1) AC System :  \n98%  \n(2) HVDC bi-pole links and HVDC back-to-back stations: 95%  \nNotes  \n(a) Recovery of fixed charges below the level of target availability shall be on pro-rata basis. At zero availability, no transmission charges shall be payable.  \n25. Incentive  \n(1) The transmission licensee shall be entitled to incentive on achieving annual availability beyond the target availability as per regulation 13, in accordance with the following formula:  \nIncentive = Annual Transmission charges x [Annual availabili~~ty ~~ achieved target availability ]/ Target availability  \nProvided that no incentive shall be payable above the availability of 99.75% for AC system and 95.5% for HVDC system.  \nAppendix-2  \n5. The transmission elements under outage due to following reasons not attributable to the transmission licensee shall be deemed to be available:  \n(a) Shut down of transmission licensee’s transmission elements availed by other agency/ agencies for maintenance or construction of their transmission system.  \n(b) Manual tripping of transmission licensee’s line due to over voltage and manual tripping of switched bus reactor as per the directions of SLDC/RLDC.  \n6. Outage time of transmission licensee’s transmission elements for the following contingencies shall be excluded from the total time of the","cbCaimEST6bvjzCq","https://ap.wps.com/l/cbCaimEST6bvjzCq","pdf",757432,159,"English","# Preface\n## Maintenance Types\n## Regulatory and Statutory Guidelines\n### Target Availability and Incentives\n### Outage Exclusions and Restoration Time","[{\"question\":\"What are the two maintenance types described in the manual?\",\"answer\":\"The manual distinguishes between preventive maintenance and breakdown maintenance.
