What is CT sensors
Current transformers (CTs) are sensors that are used for measuring alternating current. They are particularly useful for measuring whole building electricity consumption (or generation for that matter).
The split core type such as the CT in the picture above, is particularly suitable for DIY use it can be clipped straight on to either the live or neutral wire coming into the building without having to do any high voltage electrical work.

什麼是CT傳感器
電流互感器(CT)是用於測量交流電的傳感器。它們是衡量整個建築用電量(或產生對這個問題)特別有用。
分割核心類型,如上面圖片中的CT,特別適合於DIY用它可以直接在剪裁要么進入大樓現場或中性線,而無需做任何高壓電氣工作。
