GISmonitor Portable - portable partial discharge monitor

Power Diagnostix’s GISmonitor Portable is a portable instrument for the temporary monitoring of partial discharge activity on gas-insulated switchgears (GIS) caused by hopping particles, floating potentials, cracks in insulators or spacers, or other degradation in the insulation system. The instrument offers parallel real-time PD acquisition on up to 40 channels and any UHF signal can be detected and digitised within microseconds. To eliminate disturbance signals from the measurement, the GISmonitor Portable can also be connected to a disturbance antenna that provides a gating signaI. This allows the instrument to separate PD events from external disturbances in real time, providing effective PD detection. In addition, to ensure that your instrument provides reliable and precise results of the system under all harsh environmental or weather conditions, it is advisable to use the protective housing of the ICMoutlander. The GISmonitor is designed to suit all common UHF sensors for GIS PD monitoring. This includes embedded and external retrofit UHF sensors. A special input protection unit (IPU2) blocks strong transients. The frequency converter unit FCU2 demodulates UHF signals into a lower frequency band for easy submission over longer distances. The instrument can be connected to a PC or laptop via a USB port or an optional LAN interface for data evaluation and in-depth diagnosis with the GISmonitor Portable software. This service software provides easy access to view, compare, and analyse the acquired data. The current readings of up to 24 partial discharge sensors of a GIS are visualised in parallel. Each sensor is linked with a specific input channel of the GISmonitor. In addition to the standard acquisition of partial discharge versus phase position, the GISmonitor Portable software gives you the ability to acquire partial discharge at DC voltage. In this mode, the partial discharge pulses are displayed against time. Every version of the GISmonitor Portable can also be used with the software of the non-portable GISmonitor system.
