16. Maintenance Record. - (1) The Distribution Licensee shall maintain records of periodic inspections carried out in the standard formats prescribed in Preventive Maintenance Schedule. Records shall be maintained in respect of following amongst others in respective sub-station/sub-division/division office:
(a)Power Transformers and Distribution Transformers installed indoor/outdoor(b)11 kV and 33 kV Circuit Breakers;(c)33 kV and 11 kV Lines(2)Regular testing of all the equipments such as transformers, switchgear, protective relays, etc., should be carried out as recommended by the manufacturer and the relevant code of practice issued by the Bureau of Indian Standards and CBIP. These shall be carried out at the prescribed intervals and the test results shall be recorded in the maintenance registers maintained at respective sub-stations. Wherever the test results indicate a decline in the insulation resistance and/or deterioration of the equipment, preventive maintenance shall be earned out to ensure serviceability, safety and efficiency.(3)The consumers shall maintain their apparatus and power lines at all times conforming to Central Electricity Authority (Measures relating to Safety and Electricity Supply), 2010 as amended from time to time and these shall be suitable for connection to distribution system in a safe and reliable manner.5.17Environmental Issues. - (1) The Distribution Licensee shall take due regards of environment regulatory guidelines in planning, design, construction and operation of distribution system. Environmental impact assessment shall be carried out for all major distribution projects like construction of sub-stations in green and reserved area. The required clearances and no-objection shall be obtained from State Pollution Control Boards wherever prescribed.(2)The Distribution Licensee shall ensure that the environmental concerns would be suitably addressed through appropriate advance action by way of comprehensive Environmental Impact Assessment and implementation of Environment Action Plan (EAP).5.18Energy Conservation. - (1) The Distribution Licensee in order to minimise the overall energy demand shall accord high priority to energy conservation and demand side management (DSM). The Distribution Licensee shall ensure compliance of the Energy Conservation Act, 2001 and adhere to the guidelines of Bureau of Energy Efficiency issued from time to time in this regards.(2)Distribution Licensee shall ensure that the periodic energy audits wherever have been made compulsory for power intensive industries, under the Energy Conservation Act, being complied by its consumers. Other industrial consumers may also be encouraged to adopt energy audits and energy conservation measures. Energy conservation measures viz. installation of roof top solar power plants based on net metering, rooftop solar water heater and solar lighting, etc., shall be adopted in all Government buildings for which saving potential has been estimated to be about 30% of the average energy consumption.(3)The Distribution Licensee in the agriculture sector shall promote the pump sets and the water delivery system engineered for high efficiency and preferably of appropriate star labelling. In the industrial sector, The Distribution Licensee shall take action for promoting energy efficient technologies as energy conservation measures. Motors and drive system are the major source of high consumption in Agricultural and Industrial Sector. The Distribution Licensee shall advise the consumers to use high efficiency motors in Agricultural and Industrial Sector. Distribution Licensee shall take effective steps such that energy efficient lighting technologies should also be adopted in industries, commercial and domestic establishments.(4)Distribution Licensee shall endeavour that the requirements for capacity additions is reduced to the extent possible by reducing the difference between electrical power demand during peak periods and off-peak periods through suitable load management techniques such as differential tariff structure for peak and off peak supply and metering arrangements (Time of Day metering) to achieve an efficient load management.5.19Tools and Spares. - (1) The Distribution Licensee shall ensure availability of proper tools and tackles, equipments viz. megger, tong-tester, earth tester, etc., at all work places for carrying out the maintenance. The tools and tackles shall be checked from time to time and their serviceability shall be ensured.(2)The Distribution Licensee shall maintain an inventory of spares required for maintenance and replacement purposes at suitable locations according to a clear policy to be laid down by the Distribution Licensee.5.20Human Resource Development and Training. - The Distribution Licensee shall impart necessary training to its officers/staff in distribution system operation and maintenance practices so as to implement the provisions of these Regulations. The Distribution Licensee shall make appropriate arrangements for imparting training to workmen and supervisory staff, incorporating up-to-date techniques and safety measures of distribution system design, construction and maintenance. The Distribution Licensee shall prepare an annual training calendar for its officers and staff and shall submit the same to the Commission latest by 15th May of every year.5.21Geographical Information System (GIS)/Global Positioning System (GPS) based information system. - (1) The Distribution Licensee shall, in stages, deploy GIS/GPS based Geographical Facilities Information System for planning operation and maintenance of distribution system. The GIS shall be utilised for mapping the all important elements of distribution system which includes lines, transformers, sub-stations, generating stations, all unit locations and shall eventually covers all consumers. The GIS shall be linked to active Relational Database Management System (RDBMS) and GPS shall be utilised for time synchronisation.(2)The digital maps of distribution network shall be developed for each of the following preferably by conducting GPS survey which is easier, fast, accurate and economical:(a)33 kV network of complete distribution system indicating distance, type and size of conductor/size of Under Ground (UG) cable with single core or 3 core for lines and sub-station particulars with Single Line Diagram (SLD).(b)The feeder-wise 11 kV lines/cables indicating distance, type and size of conductor/ UG cable, location and capacity of distribution transformers.(c)The distribution transformer-wise LT line/cables with number of consumers and connected load of each of LT support/LT feeder pillar Box.
