Built-in sensor to switch active area
Switch from built-in sensor to built-in TEV sensor
Note : clicking this area is only valid for the built-in sensor switching. This
function is invalid when external sensors are connected. The system will
automatically switch and display the sensor icon according to the connected
sensor type, without manual selection.
The TEV probe at the front of the host is a capacitive sensor, and the
high-frequency partial discharge signal will propagate on the surface of the metal
cabinet. The frequency is generally between 3 and 100MHz. Front) and close to
the metal cabinet.
Like the ultrasonic measurement method, the environmental value needs to be
measured before the cabinet value is measured. You can measure the
environmental value at the metal plate, metal door frame, etc., and then close
the TEV sensor on the front of the host to the cabinet body to measure the
cabinet value. The difference between the body value and the environmental
value is used to judge the operation status of the switchgear.
