Power supply evaluation
During a pitch illuminance test it may be required to evaluate the power supply.
The form below should be completed with the necessary details.
The power supply for the pitch illuminance system must be reliable to ensure that matches and television broadcasts can continue without any disruption greater than what is permitted for the relevant competition category. There must be a suitable alternative backup power supply in case the primary source fails.
Please complete the form below, providing details of the power supply and other operational information.
