New IEEE Standard – Active. Identification of the key parameters that can be monitored for obtaining an indication of the condition of liquid-immersed transformers is covered by this guide. It also covers risk\/benefit analysis, sensor application, and monitoring systems application. This guide does not cover interpretation of monitoring results.<\/p>\n
