4.1.16 Pre and post-connection tests for high  voltage contestable works

The following pre-connection and post-connection tests will need to be carried out before assets installed by an ICP can be adopted:

  • Additional pre-connection tests to be undertaken by both the ICP and UK Power Networks for High Voltage Contestable Works

    • Appropriate pressure test for high voltage equipment

    • Appropriate pressure test for high voltage cables  

    • Sheath tests for high voltage cables

    • Primary & secondary injection testing to suit HV protection  

    • Test Fault Passage Indicator operation where fitted

    • Scada tests

  • Additional post-connection tests to be undertaken by UK Power Networks for High Voltage Contestable Works:

    • Voltage checks and phase rotation checks on low voltage Transformer terminations

    • Phasing check with exiting low voltage network where possible

    • Scada operations and indications
