CVT24 / CVT24-L
Precision voltage measurement for modern power networks
The CVT 24 and CVT 24-L voltage sensors are high-precision, compact devices designed for accurate voltage measurement in medium-voltage (MV) cable systems. Built to meet the latest international standards, these sensors are ideal for smart grid applications, condition monitoring, and protection systems in both onshore and offshore environments.
Key features
- Accurate voltage sensing Designed to deliver precise voltage measurements with a rated transformation ratio of 3.25/√3, the CVT 24 series supports both 0.5 and 3P accuracy classes, ensuring reliable data for metering and protection.
- Compact and lightweight design With a body length of approximately 125 mm (CVT 24) and 133 mm (CVT 24-L), and a weight of just 0.8 kg, these sensors are easy to integrate into compact switchgear and cable systems.
- Robust construction Made from brass and epoxy (RAL 8015), the sensors are built to withstand harsh environmental conditions, offering long-term durability and electrical insulation.
- Flexible installation options The CVT 24 and CVT 24-L are equipped with threaded bolt connectors (M8-3p) and support M12 and M16 mounting via thread reduction, allowing for versatile installation in various configurations.
