Section 13 in The Orissa State Electricity Board (General Conditions of Supply) Regulations, 1995
13. Inspection and testing.
(a)Upon receipt of the completion report and or the test report, the Engineer will notify to the consumer the time and the date when the Board's representative proposes to inspect and test the installations. It shall then be the duty of the consumer to arrange his Wiring Contractor to be present during the inspection to give the Engineer or his representative any information required by him concerning the installations.(b)No charge shall be made for the first test by the Engineer but for subsequent tests, if required, charges shall be imposed as provided in the Rules.(c)L. T. Consumers - (i) Before taking the Insulation tests of Installations, wirings must be complete in every respect. All fittings such as lamps, fans, cookers, motors etc., must be connected up, fuses inserted and all switches placed in the 'ON' position before the tests are carried out. Temporary wires or fittings or dead ends, shall not be included in the installations and no part of the work should be left incomplete. The insulation resistance of the entire installation to earth shall be tested from the roadside of the Board's terminals.(ii)The Board shall not connect the installations on the consumer's premises with its works unless it is reasonably satisfied that the connection shall not, at the time of making connection, cause leakage from the installations exceeding one five thousand part of the maximum current supplied to the consumer's premises.(iii)The insulation resistance shall be measured by applying between earth and the whole system of conductors or any section thereof, with all fuses in place and all switches closed and except in case of earthed concentric wiring, all lamps in position or both poles of the installations otherwise electrically connected together, a D.C. Voltage of not less than twice the working voltage provided that, it does not exceed 500 Volts for medium voltage circuit. When the supply is derived from three wire (AC or DC) or a poly phase system, the neutral pole of which is connected to earth either directly or through added resistance, the working voltage shall be deemed to be that which is maintained between the outer or phase conductor and the neutral. The insulation resistance in megohms of an installation shall not measure less than 50 divided by the number of points on the circuit; provided that the whole installation need not be required to have an insulation resistance greater than one megohm. Heating and power appliances and electric signs may, if desired, be disconnected from the circuit during the tests, but, in that event, the insulation resistance between the case or frame work and all live parts of each appliance shall not be less than that specified in the relevant ISS or, when there is no. such specification, shall not be less than half a megohm.(iv)The insulation resistance shall also be measured between all conductors connected to one pole phase conductor and all the conductors connected to the middle wire or to the neutral or to the other pole or phase conductor of the supply. Such a test shall be made after removing all metallic connections between the two poles of the installation and in these circumstances, insulation resistance between the two terminals of the installation shall not be less than that specified in para (iii) above.(d)High Tension Consumers - (i) All transformers, switch-gears and other electrical equipments in the installations of the consumer and also those directly connected to the feeders or lines of the Board, shall be of suitable design and make approved by the Engineer and be maintained to his reasonable satisfaction. The setting on fuses and relays on the consumer's control gear as well as the rupturing capacity of any of his breakers shall be subject to the approval of the Board. The starting currents of motors shall not exceed the limits as prescribed from time to time.(ii)Manufacturer's test certificates in respect of all H. T. apparatus shall be produced, if required.(iii)In addition, the Board may test the H.T. installation by applying standard test voltage in accordance with the Indian Electricity Rules.(iv)Testing of a high tension installation, shall, however, be taken up by the Engineer only after the H. T. consumer obtains the certificates of inspection of the installations from the electrical Inspector to the State Government.
