A low cost, easy to install high-voltage measuring system is described for open air substations and overhead lines. Based on the Differentiating/Integrating (D/I) principle, three free-standing capacitive pickup electrodes are used to sense the three phase to ground voltages. Apart from the individual phase aimed at, each sensor also receives a parasitic contribution from the other two phases. After integration the sensor signals therefore have to be unscrambled to recompose the original phase voltages The system has a large bandwidth, is linear and has excellent Electro-Magnetic Compatibility (EMC) properties. With its low cost, simple installation and EMC quality, the system may be incorporated easily into various applications like e.g. monitoring and line protection.
