Wilson’s microprocessor-based dynamic rating, monitoring, control and communications systems are mechanically robust, being built and tested to rugged design specifications for insulation strength, EMC capability and environmental temperature range, with self-testing and diagnosis capabilities.

Dynamic Rating allows users to work their assets harder by operating transformers safely closer to their thermal limits, thereby delaying capital investments.

Monitoring includes features such as data logging, event recording and trending. Condition monitoring features such as dissolved gas analysis, water in oil and paper insulation, bushing insulation condition and on-load tap-changer condition are being developed. Improved ability to assess transformer condition will potentially lead to cost savings from reduced risk of failure even during emergency loading, and the use of condition-based maintenance.

Control capabilities extend beyond the conventional control, alarm and trip schemes. Intelligent cooler controls increase emergency loading capability by anticipating rises in oil and winding temperature and switching on coolers earlier. Automatic voltage control now includes more options for parallel control and a wider choice of settings.

Communication via serial data links allow monitoring and control, including verification and adjustment of settings if required, from remote control locations with compatible diagnostic protocols.
