The PD Doctor system continuously measures partial discharges through specialized sensors and coupling units connected to transformers, switchboards, cables, and other electrical components. Using a patented algorithm within its Analyzer module, the system identifies weak signals, detects anomalies, and records long-term measurement histories for predictive diagnostics. It significantly reduces operational and prophylactic costs by enabling data-driven maintenance instead of routine checks.

The system also lowers technical losses by up to 20% and decreases CO₂ emissions by around 7 tons per transformer station annually. Additionally, PD Doctor can utilize medium-voltage lines as a secure alternative communication channel for power grid automation and optimization. Recommended by the Electrical and Electronic Association of the Czech Republic, PD Doctor stands out for its high user benefit, reliability, and contribution to safer, more efficient, and sustainable power network operation.
