Puncture current transformer is installed online without power failure, with built-in current transformer, electric needle, temperature sensor, diversified integrated design concept and convenient installation. It’s mainly used in power transformation and installation projects. All manual operation places are insulators, so the installation is safe, convenient and simple. When the puncture current transformer is installed, the measure line passed through the middle hole, and the current signal is output after passing through the transformer, which is converted into the required voltage signal by the sampling resistance and output as lead.
