Remreed switching networks for No. 1 and No. 1A ESS: Remreed contact and switching network evaluation

The performance evaluation of the remreed switching network begins with a study of failure modes of the remreed contact and ends with a discussion of results from a field study. Remreed contact-reliability test results show low early failure rates due to high contact resistance and contact sticking. High contact resistance, which characterizes the wear-out mode of failure, is discussed. Remreed switch evaluation results are given. Finally, early field performance of the remreed switching network is assessed in a study using in-service trunk link networks as the source of data.
