[भाग III—खण्ड 4] भारतकाराजपत्र:असाधारण 173 Schedule V Minimum safety working clearances where electricity at voltage exceeding 650 V is supplied, converted, transformed or used [See sub-regulation (2)(iii) of regulation (46)] Highest System Voltage (kV) Safety Working Clearance (Metre) 12 2.6 36 2.8
72.5 3.1 145 3.7 245 4.3 420 6.4 800 10.3
(1) The above values are valid for altitude not exceeding 1000 m. A correction factor of 1.25 per cent per 100 m is to be applied for increasing the clearance for altitude more than 1000 m and up to 3000 m;
(2) The above safety working clearances are based on an insulation height of 2.44 m which is the height of lowest point on the insulator, where it meets the earthed metal, from the ground;
(3) “Safety Working Clearance” is the minimum clearance to be maintained in air between the live part of the equipment on one hand and earth or another piece of equipment or conductor on which it is necessary to carry out the work, on the other;
(4) The “Highest System Voltage” is defined as the highest rms phase to phase voltage which occurs under normal operating conditions at any time and at any point of the system. It excludes voltage transients (such as those due to system switching) and temporary voltage variations due to abnormal system conditions (such as those due to fault conditions or the sudden disconnection of large loads).
Schedule VI Minimum safety clearances to be maintained for bare conductors or live parts of any apparatus in outdoor HVDC substations, excluding overhead lines of HVDC istallations [See sub-regulation (3) of regulation (46)] Sl.

(1) The above ground clearances are not applicable to equipment that are housed within fence or a building and where access is prevented under energised condition through a suitable safety interlocking scheme;
174 THE GAZETTE OF INDIA : EXTRAORDINARY [PART III—SEC.4]
(2) The above pole to earth clearances are for conductor-structure electrode configuration using gap factor k equal to 1.35.
(3) It is recognised that within a substation many different types of electrode configurations shall be there with different values of k, therefore, the above clearance shall be modified based upon the values of gap factor for a particular electrode configuration subjected to the minimum ground clearance.
(4) Clearance shall be provided for electrical apparatus so that sufficient space is available for easy operation and maintenance without any hazard to the operating and maintenance personnel working near the equipment and for ensuring adequate ventilation.
