operations at the rated short circuit current before maintenance or inspection is required.

22.3 Dielectric tests At zero gauge loss of vacuum inside the interrupter chamber, the open contracts

shall withstand continuously, the rated phase to ground voltage and it shall be possible to break normal current in these conditions. During the dielectric type tests, no flashover external or internal shall be acceptable.

The circuit breakers shall be subjected to a power frequency AC voltage test for

one minute in dry and wet conditions and there shall be no external flash over to earth.

22.4 Mechanical endurance In addition to the requirements of IEC:56, an extended mechanical endurance

test is required to show that the circuit breaker is capable of at least 10,000 operations at no load in accordance with IEC:17A/474/CD. Between the specified test series in IEC:17A/474/CD, some maintenance such as lubrication and mechanical adjustment is allowed and shall be performed in accordance with manufacturer’s instructions. Change of contracts is not permitted.

22.5 Duty requirement tests Apart from auto-reclosing and the other duties mentioned above, the breakers

shall be able to perform the following duties for which type tests are to be conducted as per IEC:56 or IS:13118.

1. Breaking the steady and the transient magnetising current of the transformer. 2. Breaking 25% of rated fault current at twice the rated voltage as per IEC/IS. 3. Cable charging breaking current. 4. Single capacitor bank breaking current. 5. Capacitor bank in rush making current. Test for the resistance of the main circuit shall also be conducted.

- 48 -

22.6 Temperature rise test Temperature rise test is to be conducted on the circuit breaker and the

accessories in accordance with IEC:62271-100 & 200. The temperature rise shall be limited as per this specification.

23.0 PERFORMANCE REQUIREMENTS The supplier shall declare the circuit breaker opening and closing times at 120

percent, 100 percent and 70 per cent of the rated voltage of the opening and closing devices when measured at the terminals of the trip and closing coils. The minimum make break time at rated voltage and total break time of the CB shall be stated. The total break time must not exceed 60m. sec.

24.0 EARTHING 24.1 All metal parts not intended for carrying current or not alive shall be connected

to duplicate earthing system and suitable electroplated brass earthing terminals shall be provided on each circuit breaker in conformity with IEC:62271-100 & 200. Suitable identification mark for the earth terminals shall be provided adjacent to the terminal.

24.2 The size of the earth continuity conductor shall be large enough to reduce the

potential rise of the metal frame of the breaker in the even of fault to minimum but in any case not more than 10V. The size of the conductor shall also be adequate to restrict the temperature rise without causing any damage to the earth connection in the case of fault. No riveted joints in the earth conducting path shall be permissible and only bolted joints of adequate size shall be provided with nuts, bolts and plain spring washers. The surfaces to be jointed shall be perfectly flat without any unevenness to ensure that there is no contact resistance.

24.3 An earth busbar of copper strip shall be provided inside the local control cabinet

to which all earthing connections must be made. The earth busbar shall be terminated into two electroplated brass earthing terminals of adequate size with nuts, bolts and washers for connecting to earth continuity conductor mentioned above.

25.0 Mandatory Spare Parts for 11KV Indoor VCB. The supplier shall provide the mandatory spare as follows for every 20 panels.
