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

.
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
