PD Guard – The doblePRIME PD-Guard™ monitors partial discharge (PD) in equipment such as transformers, rotating machines, cables and switchgear and provides local alarms and will communicate data and notifications across standard interface channels and through to networked supervisory systems. It analyses PD and EMI signals in the HF, VHF and lower UHF ranges.
IDD – The doblePRIME IDD™ bushing monitor detects deterioration in bushings, finding abnormalities in the insulation and issuing actionable alerts and provides leakage current and phase analysis for up to 6 bushings, measuring parameters for each bushing individually, and using a voltage reference where available.
IO – The doblePRIME iO is a data recorder that accepts current, voltage, temperature and relay inputs to your doblePRIME system and integrates and displays data from multiple sensors and sources, including load or operational data, tap position indicators and inputs from other vendor devices.The Calisto T1 can build from a single component to a comprehensive transformer monitor covering partial discharge (PD), bushings, operational data, and linking to Dissolved Gas Analysis (DGA) monitors.
Examples of asset saves, including transformers and generators, are available in Doble technical publications.
