TT Series – Split Core Current Transformers with Cable Output
The TT Series split‑core current transformers are engineered for accurate measurement of AC currents in applications where installation flexibility and compact integration are key requirements. Designed with air‑core current transformer technology, TT sensors ensure galvanic isolation between the primary and secondary circuits and are primarily intended for energy, smart grid, and automation applications.
Unlike the AT Series, TT current transformers are delivered with a 1‑meter cable output, simplifying installation in confined or remote measurement locations. They are available with 8 mm or 16 mm aperture diameters, allowing adaptation to different conductor sizes.
The TT Series focuses on straightforward deployment and reliable AC current measurement in distributed monitoring systems where cable‑based connection is preferred.
TT – Features and benefits
Main characteristics
- Split‑core current transformer for non‑intrusive current measurement
- Available with 16 mm or 8 mm sensing aperture, offering flexibility for different conductor sizes
- 1‑meter cable output, enabling flexible current sensor placement away from control electronics

Benefits
- High total error and low phase shift, supporting accurate power calculations
- High insulation between primary and secondary circuits
- Compact and lightweight design
- Cost‑effective and easy to deploy
Typical applications
In addition to general energy and automation use cases, the TT Series is particularly suited for:
- Power meters: Current measurement for active power calculation
- Energy sub‑metering: Energy efficiency monitoring, consumption analysis, and cost allocation
- Power quality monitoring
- Distributed measurement systems, where cable‑based connection simplifies installation
The TT Series is ideal when measurement points are dispersed and installation flexibility is a key requirement.
