SAM 3.0 sensitively records electrical surges from lightning and switches, as well as total leakage current. These values are displayed in digital form on an electronic display. It consists of a current sensor with an optional cable length and a display device that can be installed outside the arrester.
The system divides the inrush current pulses into three categories and saves overvoltage events with time and date information (time stamps).
Application program
Suitable for all types of AIS and GIS gapless arresters in medium and high voltage power grids
Especially recommended for hard-to-reach installations (switchgear, medium voltage switchboard, overhead lines, etc.)
Why choose Hitachi Energy?
Accurate total leakage current measurement
Safe behavior is demonstrated even after overloading the surge discharger
Use time stamps to classify surge events
No voltage is added to the residual voltage of the arrester
Split mounting - the display can be located away from the measuring point
EMC robust design
Easy to install
Applications:
profession
