GSA Current Transformer

GSA cast resin current transformers can be used for a variety of measuring, revenue metering (billing) and protection tasks. If the busbar systems or medium voltage cables are sufficiently insulated, these current transformers can be used for insulation levels higher than Um=0,72KV (Highest voltage for equipment Um). The ring-type current transformer for outdoor use is also available on request (GSAF).
