6.2 Reliability of Communications and Systems A number of DGCM substation monitors have experienced communication issues; these have been linked to incorrect settings and no real communication issues are outstanding. Signal strength in a substation environment has not proved to be a constraint other than that the aerial has to be mounted outside of the low voltage pillar or cabinet, even if the DGCM could otherwise be mounted inside the cabinet. 6.3 Reliability of Pi ProcessBook There have been no reliability issues with the Pi ProcessBook database in the period of operation to date. Pi ProcessBook as a pre-existing system is of proven reliability, and some modifications to the configuration established for NTVV are to be expected over the next few months. 6.4 Reliability of Data Received by the University of Reading The University of Reading will review the quality of data received in terms of completeness and error checking on an ongoing basis. To date, as more substation monitors have been commissioned refinements have been made to ensure that all parameters are reliably reported, and further refinements are expected to be required as the data is analysed in detail over the next few months. Apart from some initial setting up issues the University of Reading have confirmed their satisfaction with the data. 7 Appendices Appendix 1 Substation Categorisation See separate document attached.
