Technological advancements related to the protection system of the electrical power grid have enabled utilities to utilize information previously not available. Through the integration of microprocessor-based relaying and the expansion of the communications network, the electric system has seen great advancements in both complexity and robustness. Although methodologies related to periodic maintenance-based testing in electromechanical and solid-state relaying were widely accepted, microprocessor-based relaying has posed many philosophical debates related to what should be performed and what should be required. The opinion of the industry has begun to move away from performing periodically based element testing, to the desire to perform conditional based acceptance testing; verifying only the health of the equipment and to satisfy the requirements set forth by the federal government. One mindset that remains from past industry practice is performing acceptance testing locally, taking the asset out of service to do so. Performing this work locally imposes many logistic challenges to all those involved. In order to achieve a higher level of efficiency and reduce logistical burdens, automated control systems and data dissemination solutions become a necessity. This work proposes an automated system comprised of: hardware that enables remote verification of the protection system while equipment remain energized, and the use of the communications system in conjunction with scripting software written to control the system and disseminate the data effectively and efficiently. These methods are applied to leading relaying technologies in the power utility industry. Simulations on a laboratory grade installation are conducted to demonstrate the effectiveness and 'proof of concept' of the proposed automation methodologies.
