* Reference only. Configurations and details may vary depending on the application scenario.

1. Summary

TD3730 is a device specially used to test the influence of industrial frequency strong magnetic field on electric energy meter. It consists of power frequency excitation current source, power frequency magnetic field generator and handheld alternating magnetometer.

2. Features

• The power frequency magnetic field generator is excited by the excitation current source to generate a 0-100mT programmable power frequency magnetic field.

• The power frequency magnetic field generator can generate a large power frequency magnetic field within the range of 70 mm × 35 mm.

• The magnetic field strength of the testing point can be tested by scanning the magnetic field with the coil probe of the handheld alternating magnetometer.

• The power frequency magnetic field is applied to the six faces of the electric energy meter to be tested, and the user's electric energy meter calibration device is used to complete the test of the influence of the power frequency strong magnetic field on the electric energy meter error.
