FIELD: physics.
SUBSTANCE: device for measuring vibration of high-voltage elements contains a measuring head in form of a hollow dielectric body in which there is an elastic member, one side of which is attached inside the body, and an inertial mass is attached to the opposite end of the elastic element. The output of the measuring head is joined by a dielectric pipe to the input of the measuring unit, which has an amplifier, the output of which is connected to an output signal conditioner, the output of which is the output of the device for measuring vibration of high-voltage elements. The elastic member is in form of an elastic chamber at the point where the measuring unit is mounted. The measuring unit has a pressure sensor, the input of which is the input of the measuring device. The output of the pressure sensor is connected to the input of the amplifier.
EFFECT: possibility of measuring in a wide frequency range, including low and infralow frequencies and wider field of application due to lower restrictions on the level of vibration.
