Voltage sensors

Ohmic, Capacitive & Resistive-Capacitive Medium Voltage Sensors (12 kV // 24 kV // 36 kV // 72 kV)

At INDISOL, we design and manufacture medium voltage sensors for applications from 12 kV up to 72 kV, combining precision, safety, and reliability. With more than 15 years of experience developing customised solutions for industry leaders, our sensors are trusted components in modern power distribution systems worldwide.

Our technologies ensure measurement precision as high as 0.2%, meeting the demanding requirements of today’s power systems.

We offer three main medium voltage sensor types to meet different application needs:

• Ohmic Voltage Sensors – Based on resistive dividers, these sensors deliver highly accurate and stable measurements (with a precision of up to 0.2%), making them ideal for protection relays, monitoring systems, grid automation, advanced diagnostics, and predictive maintenance applications. Their robust design ensures reliable long-term performance with minimal maintenance requirements.

• Capacitive Voltage Sensors – Using capacitive dividers, these sensors provide a compact and cost-efficient solution for voltage presence indication, fault detection, and monitoring. With low power consumption and small dimensions, they are particularly suitable for integration into switchgear, cable accessories, and smart grid applications.

• Resistive-Capacitive Voltage Sensors – Combining both resistive and capacitive divider principles, these hybrid sensors offer a versatile solution that balances accuracy, compact design, and energy efficiency. They are ideal for applications requiring precise measurement while also enabling voltage presence indication and monitoring functions within the same device.

Whether you require ultra-precise measurement (up to 0.2%), cost-effective monitoring, or multifunctional hybrid solutions, INDISOL develops tailored medium voltage sensor technologies to support the safety, efficiency, and innovation of your medium-voltage network.
