![]() ![]() Along with the standard glass disc profile, two strings of glass fog profile (the one coated with RTV) and two long-rod composite insulators of different shed profile and material were used. Five different insulators were selected based on the types historically used in the Cretan Network. Multiple measurements were performed on each insulator every month in order to collect additional data. In order to investigate the pollution accumulation and the impact of natural washing on different insulator types, a series of periodical ESDD and NSDD pollution measurements were conducted in HEDNO’s TALOS High Voltage Test Station for a 3-months period. Polymer coatings have also been extensively applied on substations and also on certain areas/towers of the transmission network in the past. Following the positive feedback after the installation on certain tower in the past, a large project to replace all ceramic insulators with new polymer ones of hydrophobic surface is now in progress. The Greek utility has employed a variety of remedies to cope with the pollution problem. A rather interesting case in Greek territory is the island of Crete, due to the coastal development of the network and the local weather conditions. Utilities perform such measurements in order to decide upon the location/route of new HV installations (substations, lines etc) and also to optimize the selection, maintenance and replacement of already installed insulators. Environmental influence is rather important for the optimum selection of outdoor insulators and, therefore, field measurements provide valuable information. Reliability is a key issue for electric power systems and fault-free performance of insulators greatly reflects on the reliability of the system. A 2D version is available for a higher price.High Voltage insulators are scattered throughout any HV network and a single insulator fault may cause an excessive outage. If you need simple 1D processing, this is the most affordable software. NUTS This program can run both on Windows and Mac computers.For users that are members of the WSU chemistry department, directions on installing this software can be seen here. The WSU chemistry department currently owns a departmental license to this software. MNOVA from Mestrelab Research has more than one flavor of this software available for purchase and one can also download a trial version by registering.Interface is user friendly and can read many NMR fid formats including Bruker’s. ![]()
