Enhancing grid reliability with precision and safety in a compact design for switchgears up to 36 kV.
The TE Connectivity (TE) Kries CAPDIS-4o voltage amplifier provides precise voltage detection for modern electrical installations. This addresses challenges such as limited space, ferro resonance risks, and the need for reliable voltage monitoring without extensive system modifications.
Traditional voltage transformers can be bulky and pose safety risks, which can complicate maintenance. The CAPDIS-4o outputs 3x100 or 110 VAC using three resistive sensors, serving as an economical and precise alternative to inductive voltage transformers. It connects to protective relays with 100 VAC inputs, measuring devices and network analyzers, making it ideal for critical safety applications. Its compact design also allows for easy retrofitting in confined spaces.
An accuracy class of 0.5% for the entire circuit is ensured when it is combined with voltage sensors (amplifier 0,3 % + voltage sensors 0,2 %) and installation is straightforward - requiring no additional measuring fields or disassembly for surge voltage tests. The CAPDIS-4o is compatible with ohmic dividers for air-insulated switchgear (12 kV, 24 kV and 36 kV) and resistive dividers for SF6 switchgear (12 kV, 24 kV and 36 kV on request).
Offering accurate voltage detection, while also avoiding ferro resonance hazards, increases operational safety. The compact size of the CAPDIS 4o makes it easy to retrofit into existing setups without significant changes. Additionally, this design minimizes maintenance efforts and costs, providing a cost-efficient and dependable alternative to traditional voltage transformers.
