Description
Overview
The Voltech CT1000 is a toroidal AC current transformer designed to extend the range of Voltech power analyzers such as the PM100, PM300, or PM3000A to 1200A rms. Close-tolerance current ratios provide measurement accuracy better than 0.2%, making it suitable for precision-grade measurements.
The CT1000 is housed in a fully insulated, shock-resistant casing with a core aperture that accommodates large-diameter cables or rectangular busbars. For safety, it features 4mm safety sockets for connecting to power analyzers, and an over-voltage protection circuit that limits output voltage to 50V peak if the secondary winding is inadvertently open-circuited.
Key Features

- Maximum continuous input current of 1000A (2000A for 1 hour)
- Phase error better than ±0.1° at 50Hz
- 4mm safety sockets for secure connections
- Over-voltage protection limiting output to 50V peak
- Dielectric strength of 4kV at 50Hz for 1 minute
Applications
- Power quality analysis
- Energy measurement and monitoring
- Precision current measurements in industrial environments
