Sažetak
This article presents an active fault detection kit, applicable to low voltage single-phase electrical
installations, in the prospect of the Zero Energy Building concept, integrating on-site renewable energy generation and energy storage. This simple, flexible, self-powered and compact
kit is capable of detecting faults, such as power theft (meter tampering), unintentional islanding and neutral conductor loss. Its operation is based on harmonic voltage injection, in series
with the electrical installation, through a low-power H-bridge inverter and a current transformer,
along with the corresponding harmonic current measurement, to estimate the impedance and
effectively detect faulty conditions; the fast and robust Goertzel algorithm is utilized. Moreover,
it features IoT communication capabilities, employing the ESP32 microcontroller, to exchange
data and information with the installation meters. The functionality and effective fault detection
of the proposed device are validated, through experimental tests on a custom-developed hardware prototype; IoT connectivity and data uploading are experimentally tested and verified, too.
Finally, a sustainability assessment study is performed, using the Life Cycle Cost Analysis tool.
