Resistive Capacitive Voltage Sensor

Resistive Capacitive Voltage Sensors (RCVS) for Medium Voltage Switchgear

Indisol has designed this Resistive capacitive voltage sensor (RCVS) to provide an accurate and reliable image of the voltage on the high-voltage line. As a result, they are ideal for measuring network conditions and determining the source of faults in medium-voltage systems.

Moreover, RCVS achieve accuracy levels ranging from 1% up to 0.2%, ensuring ultra-precise monitoring. In addition, they operate reliably across a wide frequency range. Consequently, engineers can depend on their stability and precision in demanding applications.

Unlike conventional instrument transformers, RCVS units do not contain saturable cores. Therefore, they cannot fall into ferroresonance, significantly improving operational safety.

RCVS 

For 17, 24, 36, 52, and 72 kV medium-voltage networks

Suitable for indoor applications, particularly in:

• Voltage measurement in switchgear assemblies

• Fault detection and localisation in distribution grids

• Digital substations and smart grid systems

• Protection and monitoring equipment requiring precise signals

Design options include:

• Accuracy classes from 1% to 0.2%

• Cylindrical or conical shapes

• Interfaces compatible with standard measuring and protection devices

• Custom dimensions available for retrofit projects

Summary

In conclusion, INDISOL’s RCVS combine precision, safety, and adaptability. Consequently, they guarantee reliable voltage measurement and fault detection while preventing ferroresonance issues. Whether used in new installations or retrofit projects, RCVS provide engineers with a modern, robust, and future-proof solution for medium-voltage networks.
