The use of advanced low-power sensing technologies instead of traditional solutions used in the distribution, measurement and control of the power grid has introduced core instrument transformers due to their physical limitations and other reasons. This situation has also brought about the design of low-power voltage transformers. As can be understood from here, analogue measurement and control systems used in power centres are approaching the end of their useful life. This substations need digital automation solutions and new technologies for more efficient performance. Since no iron core is used in the low-power electronic voltage transformer structure, it is robust against network disturbances such as ferroresonance and ferroresonance formation is not encountered. In this study, a low-power electronic voltage transformer is designed and performed experiments are presented. The most essential feature expected in a voltage sensor is that the conversion rate is precise and unchanging. For this reason, the temperature coefficient and leakage capacitance values of the voltage sensor have been designed to have the lowest margin of error. Performance tests were applied to the voltage sensor using mains frequency endurance, partial discharge, accuracy class, linearity and temperature distribution tests. The results of the performance tests show that it has been successfully applied for the design of a precision voltage sensor with an accuracy class conforming to the IEC 61689-11 standard.
