Abstract

The product digitalization is nowadays part of almost any product development, so that the digitalization of air insulated high voltage disconnectors and earthing switches will be introduced. The motivation by consequences for the product installation and maintenance are given and necessary considerations for the different available and required operation methods of the product are included. Possible data sources within the product are categorized and applied use cases are explained. The possible use cases are covering the switching position, counted operations including forecasting and the monitoring of the anti-condensation heating, as simple use cases. Those are complemented by highly beneficial use cases, as the more known and expectable motor current monitoring and the overcurrent allowance, which is driven by the indirect proportionality of a temperature rise at one current value to a temperature rise of a second current value and the resulting quotient of both currents to the same potency, as per IEC TR 62271-306. The overcurrent allowance use case may not be as expectable, since the IEC reference is not directly related to disconnector and earthing switches, and therefore its underlying calculation methodology is explained and elaborated in detail with boundary conditions and its visualization by a case example. The calculated temperature rise factor is introduced and different safety margins are highlighted. Further use cases with information about realization complexity and potential benefits are complementing the product digitalization possibilities and opportunities. Finally, the applied use cases are illustrated by an executed example of a digitalized center break disconnector.
