The VxxxC-xx voltage sensor is engineered for integration into T-connectors, typically replacing blind plugs to offer dual functionality: securing the connector and enabling precise voltage measurement. Designed to meet EN 50181 standards, it is compatible with a range of T-connectors from various manufacturers. The sensor's design incorporates a common earth connection point and an output cable for interfacing with intelligent electronic devices (IEDs). This sensor supports a wide temperature range, making it suitable for varied environmental conditions. Its application is critical in setups that require both mechanical and electrical functionality without compromising connector security. By eliminating the need for separate installation of measurement devices and blind plugs, it offers a streamlined solution for efficient energy transmission systems, especially in settings where space and reliability are key considerations.

The ExxxR-xx current sensor is specifically designed for integration on the bushings of gas insulated switchgear utilized at the secondary energy distribution level. Featuring a compact form factor, it accommodates a variety of T-connectors, making it versatile for different installation scenarios. This sensor employs passive technology, eliminating the need for active components and external power supplies. Its splitable design allows easy retrofit installations on existing bushings and cables. Earthing options include direct connection at the sensor, via the cable shielding, or through the IED's S2 connector. The device provides correction factors to improve amplitude and phase accuracy, ensuring high-class sensor performance. Additionally, an ECO-variant is available which initially operates at accuracy class 1 but can be enhanced through specific correction factors. For robust applications, the sensor can be equipped with an IP67 protection rating, safeguarding against environmental ingress. This makes it a reliable choice for demanding electrical infrastructure environments.
