Pollution Mapping for Southern Region Meeting of coordinators at Bengaluru 30th October2013 Agenda Pollution mapping for Southern region Pollution mapping program is proposed for Southern Region using methodology similar to mapping program of Northern region Pollution Mapping shall be carried out through CPRI The mechanism/methodology which shall be adopted for present project is as shown in subsequent slides Measurements to be done/Training Two Measurements shall be carried out Equivalent Salt Deposit Density (ESDD)& Non Soluble Salt Deposit Density(NSDD); and Layer Conductance Measurement Training (including hands on) shall be provided to the associated engineers of CTU/STU by CPRI The training shall be carried out at approx.10 Nos. of locations – Locations to be decided in consultation with SRPC/Coordinators Trained persons to carry out the pollution measurements Instruments for the Measurement Instruments required for the measurement shall be procured and distributed by CPRI There shall be two sets of instruments one for ESDD/NSDD and another for Layer conductance measurement (which is to be conducted on only 10% of sites) 1 set of instrument each is required for approx. 10 Nos. of sites for the ESDD/NSDD measurement 30 Nos. of sites for the Layer conductance measurement The final number of instruments required and the list of addresses where the instruments have to be dispatched shall be finalized in consultation with the STU/CTU coordinators Action Points Nomination of Coordinators and an alternate coordinator, each from each state utility, SRPC and PGCIL (Name, Correspondence address, e-mail, mobile no./Tel no., fax) Identification of sites to install the dummy insulators for the measurements has to be done by POWERGRID and State Transmission Utilities in their respective lines A grid of 25km × 25 km is marked on the map then at least one location is identified which falls inside each grid (Grid coordinates to be distributed). For the locations which fall in the coastal region or have high pollution, instead of a single location in each grid, two locations in each grid are to be identified. No. of locations POWERGRID Kerala: Grids in which STU has to identify towers: 196 Tamil Nadu: Grids in which STU has to identify towers: 46 Karnataka: Grids having POWERGRID towers: 287 Grids in which STU has to identify towers: 91 Andhra Pradesh: Grids in which STU has to identify towers: 207 Action Points Contd… . On identification of locations, the distributed format has to be filled and sent to CPRI, Bengaluru alongwith a copy to POWERGRID, TD Department so that the locations are finalized after scrutiny Action Point – 4 On the 10% of finalized location Layer conductance Measurement has to be conducted. Electricity supply is required at these locations (under the tower where the dummy insulator shall be installed) These sites have to be finalized by the site on the basis of operational easiness. Action Point – 5 Installation of dummy insulators POWERGRID and the respective State Utility shall arrange for dummy insulators (20 discs per location where both ESDD/NSDD and Layer conductance measurement has to be done and 10 discs per location where only ESDD/NSDD measurement has to be done) Installation of these insulators on Transmission line towers at identified locations. Action Point – 6 The surface area of the insulator to be installed has to be determined. For that following is suggested: As far as possible same type of insulators should be installed throughout the region If possible, the surface area (top surface and bottom surface) may be enquired from the manufacturer itself Otherwise, during the conduction of training program at various locations, one sample of each type of insulator to be installed may be brought for surface area measurement by CPRI officials. Action Point – 7 Instruments for the ESDD/NSDD and Layer conductance measurement shall be procured and distributed by CPRI The coordinators shall indicate the number of instruments required and prepare the list of addresses where the instruments have to be dispatched. There shall be two sets of instruments one for ESDD/NSDD and another for Layer conductance measurement (which is to be conducted on only 10% of sites). Measurement/Analysis Contd… CPRI shall analyze the measurements / results of test carried out at site & laboratory and determine the pollution levels Pollution map shall be produced on Survey of India geographical map of suitable scale CTU/STU shall arrange dummy insulators, necessary manpower and instruments required for installation of dummy insulators and carrying out measurements at site Measurement/Analysis Contd… Instruments required are: Digital conductivity meter ESDD/NSDD Digital Physical balance (mg range) Digital micrometers Layer 2.5mX2.5mX3.0m tent & heater for fogging Conductance arrangements (only for Variable 2kV source 10% of the locations) Scope Criterion for site selection (inline with Recommendation of CPRI) Training of CTU/STU Personnel Measurement/Analysis At site by CTU/STU Personnel Laboratory measurement/Analysis (by CPRI) Development of Pollution map of Southern Region Development of Pollution map of Southern Region CPRI shall carryout the analysis of test result and estimate and map pollution levels geographical map of Northern Region Flow chart of activities Sample Pollution map of Italy Thank You for Your kind Attention
