    Sir,
    I am a regular reader of your articles. It is too informative.

    The recommended phase to phase and phase to ground clearance on 11kV DP structure is 915mm and 610mm respectively. Please be kind enough to inform, from where (standard or rule) this value is derived.

    Good morning, Please clarify how to calculate the main power source of the connected load is about 3000 kW

    What should be the main power source capacity and other factors to be considered

    Thanks Best regards Srikanth
