Test equipment of very low weight which is frequency-tuned within a regulation range of one to two times the power line frequency has been built. It differs from all common series resonant testing equipment in that it makes use of rotating alternator modules for current injection into series-connected inductors and parallel-connected capacitors forming a kit system. The kit idea is illustrated by several module designs which cover a range of voltage and power ratings that correspond to a series of testing transformers. The testing kit allows on-site testing of GIS substations or other large-scale applications by standardized LC coupling. As examples show, important applications are also found in the fields of cable testing and of transformer testing, both on site
