Spark P3 comes with an automatic signal classification system that enables users unfamiliar with PD and EMI signal characteristics to obtain reliable results by helping them differentiate these signals from nuisance signals.
FREMONT, CA: Doble Engineering Company, a leader in power grid diagnostic solutions and subsidiary of ESCO Technologies Inc., announced the release of the Spark P3, a universal partial discharge (PD) and electromagnetic interference (EMI) analyzer. The new device enables users across all experience levels to easily perform comprehensive PD and EMI insulation system diagnostics and analysis on a wide range of high voltage apparatuses, including rotating machines, power transformers, instrument transformers, switchgear, cables, and accessories.
The instrument uses a software-defined radio signal detector to identify characteristics of insulation system deterioration that could lead to the failure of high voltage equipment. The detector is configurable to suit any sensor with a frequency range between 9kHz and 2 GHz for PD and EMI and DC to 500kHz for acoustic and reference voltage measurements. With a wide range of advanced diagnostic tools, including phase-resolved PD analysis, spectrum analysis, time-resolved narrow band analysis, and automatic rotating machine insulation system defect assessment, end-users are equipped to detect emerging faults early and avoid outages and other damages.
"Traditional testing approaches rely on a wide range of sensing methods and require a trained expert to help interpret the results, which can make it difficult to diagnose partial discharge and electromagnetic interference characteristics quickly," said Falk Werner, solutions manager at Doble Engineering Company. "We've designed this new universal analyzer to automatically take measurements, classify signals, analyze the data, and more, so teams can focus on acting on the results instead of the intricacies of the measurements."
Spark P3 comes with an automatic signal classification system that enables users unfamiliar with PD and EMI signal characteristics to obtain reliable results by helping them differentiate these signals from nuisance signals. The algorithm also assists with classifying different types of PD and EMI defects based on their signal characteristics. "Wizard Mode" guides newer users through measurement and data acquisition procedures with an intuitive user interface that excludes any unnecessary elements and functionality, while "Expert Mode" allows more experienced users to utilize the system like a traditional laboratory device, which can be configured to perform measurements in any desired form.
Doble's Spark measurement systems will integrate with Doble Pulse companion PC software, enabling the user to manage measurement data, edit test plans and asset information, visualize measurement data, and export individual data sets or entire test plans to report templates.
The analyzer also includes configurable, pre-set test plans and measurements, making it ideal for a broad range of users, including utilities, field testing companies, large industrial organizations, universities, and laboratories. The lightweight, portable, and battery-operated device is suitable for both benchtop and on-site settings. A 19-inch rack-mount adapter is also available. The device includes multiple input channels, including two PD, two reference voltage, and two acoustic emissions channels, and comes with a 100-240V 2A power supply.
