Contactless Voltage Measurement with SMF Technology
Suparule has developed a new sensor technology which will enable the measurement of alternating voltage in a conductor, e.g. an overhead AC Power Line.
The sensor is based on the positioning of capacitive sensors in a circle around the conductor. The electric field created by the voltage between the conductor and ground induces a voltage in the capacitive sensors, which is proportional to the electric field of the conductor. Using minimal electronics, the voltage on the conductor can be calculated, as well as rejecting the influence of fields associated with adjacent conductors.
- Contactless measurement of voltage of overhead lines
- Inexpensive to manufacture
