Doble Launches Spark P2 Handheld PD Detector With UHF, HF and Acoustic Sensors
Doble Engineering introduced the Spark P2 handheld device, offering narrow-band UHF, HF, acoustic, and ultra-wide-band charge detectors for comprehensive partial discharge and RFI analysis. Weighing less than a laptop and fitting in a briefcase, the device delivers phase-resolved, spectrum, and time-resolved diagnostics to reduce unplanned high-voltage asset outages.
1. Product Release and Strategic Fit
On March 30, 2026, Doble Engineering, part of ESCO Technologies Inc., unveiled the Spark P2 handheld partial discharge and RFI measurement device. This release expands ESE’s diagnostic solutions portfolio by introducing a compact, field-ready tool designed for universal PD testing across power grid assets.
2. Advanced Diagnostic Features
The Spark P2 integrates narrow-band UHF, HF, wide-band acoustic, and ultra-wide-band charge PD detectors, along with phase-resolved, spectrum, and time-resolved analysis capabilities. It offers both ‘Wizard Mode’ for guided measurements and ‘Expert Mode’ for advanced configuration, enabling users of all skill levels to perform detailed insulation diagnostics.
3. Market Impact and Applications
Weighing less than a laptop and fitting into a briefcase, the Spark P2 targets substation surveys, transformer and switchgear testing, and cable accessory assessments. By enabling early fault detection and seamless data integration with Doble Pulse software, the device helps utilities, industrial operators, and service firms expand PD diagnostics offerings and mitigate unplanned outages.
