TD3730 Electric Energy Meter Working Frequency Strong Magnetic Field Test Device

TD3730 Electric Energy Meter Working Frequency Strong Magnetic Field Test Device ◉ TD3730 is a set of devices specifically designed to detect the impact of working frequency strong magnetic fields on the tested meter. It mainly consists of a working frequency excitation current source, a working frequency magnetic field generator, and a handheld alternating current magnetometer. The device is excited by a working frequency excitation current source to the magnetic field generator, generating a programmable and continuously adjustable working frequency magnetic field of 0-100mT within a range of 70 mm × 35 mm. And scan the magnetic field through the coil probe of a high-sensitivity, low drift handheld alternating magnetometer to determine the magnitude of the magnetic field at the detection point. Apply the working frequency magnetic field to the six sides of the tested meter, and use the calibration device of the tested meter to complete the test on the influence of the working frequency magnetic field on the error of the tested meter. The overall transmission power of the device is small, and it adopts cooling and heat dissipation, which is low-carbon, environmentally friendly and energy-saving.
