Capacitive Voltage Transducer

The Capacitive Voltage Transducer is a medium and high voltage sensing device designed based on the capacitive voltage divider principle. It is specially developed for voltage measurement, protection and metering scenarios of medium and high voltage distribution systems, and can be used together with our switchgear such as circuit breakers and reclosers to realize accurate collection of line voltage. This product adopts a capacitive voltage divider structure, without iron core design, no magnetic saturation problem, good measurement linearity and wide frequency response range. It can accurately collect steady-state and transient voltage signals, and provide reliable voltage data for protection devices and metering systems. As the core sensing component supporting switchgear, the Capacitive Voltage Transducer has excellent insulation performance, can be directly installed on medium and high voltage live bodies without additional insulation adaptation, and is the core device for voltage sensing in smart distribution grids.

In terms of performance and adaptability, this capacitive voltage transducer adopts high-precision capacitive elements, with good temperature stability and high measurement accuracy, and can maintain stable measurement accuracy in a wide temperature range. The equipment adopts an integrated insulation casting structure, with good sealing performance, waterproof and dustproof, high protection grade, and can operate stably for a long time in harsh outdoor environments. In response to the application scenarios of medium and high voltage switchgear, we have optimized the installation interface and output signal of the product, which can be seamlessly connected with our circuit breaker and recloser products, and also adapt to third-party switchgear and protection devices. At the same time, we can provide customized configurations according to customers' voltage levels, accuracy requirements and output modes to meet the differentiated sensing needs of different projects.
