Doble Spark P3 is a universal partial discharge (PD) and electromagnetic interference (EMI) analyser that uses a software defined radio signal detector to identify characteristics of insulation system deterioration that could lead to the failure of high voltage equipment.
It detects signals from suitable sensors in a frequency range between 9 kHz to 2 GHz for PD and EMI, and dc to 500 k Hz for acoustic and reference voltage measurements.
A comprehensive range of detectors, acquisition and analysis tools enables users at all levels to acquire and review partial discharge and EMI signals, covering a range of test objects and usable sensors. These include:
- Rotating machines (PD couplers, HFCT sensors)
- Power transformers (HFCT sensors, UHF antennas, acoustic microphones)
- Instrument transformers (HFCT sensors)
- Switchgear (GIS and AIS – TEV sensors, UHF antennas, HFCT, acoustic sensors, spacer sensors, window sensors)
- Cables and accessories (HFCT, UHF sensors, acoustic sensors).
