CTW10 Clamp-On Current Transformer

Brand: Yokogawa Electric Corporation

The CTW series are clamp-on current transformers that can be installed much easier than conventional current transformers, whereby saving labor.

These transformers are particularly useful when expanding existing system since you can attach them to a cable without having to cut it.

  • The clamp-on type makes the installation much easier for both existing and newly-established systems.
  • Being able to fix the transformer to power line directly enables users to select the installing point comparatively freely.
  • The CTW series contain a device for suppressing hazardous voltages that may arise when the secondary line is open-circuited. It prevents a burnout or outage.
