1. Summary

TD3700 is a device specially designed to test the impact of AC magnetic field on energy meters. It consists of AC excitation current source, ring coil, DUT workbench, motor control system, three-phase energy meter testing device, computer and automatic test software etc. The device can generate a programmable and adjustable power frequency AC magnetic field of 0 to 1200 A/m. It can be used with the energy meter testing device to complete the power frequency magnetic field test and power frequency magnetic field interference test of the energy meter.

2. Features

• The ring coil is excited by a precision AC current source to generate a power frequency AC magnetic field with a magnetic field of 0 to 1200 A/m and a programmable and adjustable power phase of 0 to 360°.

• The ring coil and the platform of the meter under test are controlled by precision stepper motors and can rotate from 0 to 360°;.

• The rotation angle is controlled by the computer to facilitate the application of AC magnetic field to all directions of the electric energy meter under test.

• The phase of the AC magnetic field and the working voltage of the electric energy meter under test can be adjusted arbitrarily within the range of 0~360°;.

• The system is equipped with computer testing software, which can complete fully automatic and semi-automatic tests of the impact of AC magnetic field on electric energy meters.

• The automatic testing include: automatically adjusting AC magnetic field; automatically calibrating the error value and magnetic field influence of the energy meter at each calibration point; automatically controlling the rotation of the ring coil and the platform of the meter under test.

• The software has complete data management functions, convenient data retrieval, and automatic backup functions.

• The software can output statistical reports such as calibration certificates and test reports.
