Indoor Split-core CT

Split-core current transformers are designed to meet the growing demand for installation into the existed grid. It's ideal for retro-fitting. Parameters will be measured and compared without power supply cut-off on account of the split core, so it's popular in the energy management system and power factor correction. It can be used along with many kinds of instruments and devices.
