If a meter has no possibility to open the internal link between voltage and current
When do I need Isolation Current Transformers?, the test must be performed with an Isolated Current Transformer (ICT) at each measurement position.
The CL2030-D has a built-in electronic compensation. The ICTs can be remote controlled by PC. A safety protection by controller is built in. This assures that the secondary side is closed in case of high burden or open circuit. Each ICT will be delivered with a company calibration certificate. A certificate issued by an ILAC accredited laboratory is optional available.

Accessories
The ICTs can operate stand-alone or together with a remote control by PC. For remote control with 3rd party equipment, a control box CL2030-3D-CB is needed. An interface-description is available on request.
The links are uses to interconnect the primary side of ICTs. The copper links are galvanized. These links are designed to connect ICTs with a centre to centre distance of min 297 mm and max 317 mm.
If you are test equipment manufacturer you can get the ICT2030-D with your company-logo and without any CLOU indication from outside visible.
