Embodiment 2
[0070] This embodiment provides a method for multi-channel dielectric loss measurement. The method of this embodiment can be performed by the multi-channel dielectric loss measurement device of the above-mentioned embodiment. The method also includes:
[0071] The process controller controls the on-off state of the first switch and the second switch and the conduction state of the first end, the second end and the first test end, the second test end and the third test end in the switch module, so that the circuit under test Different capacitors to be tested and the bridge module form a bridge circuit, and the capacitance value and dielectric loss value of the capacitor to be tested are calculated according to the bridge circuit.
[0072] Optionally, the process controller acquires the readings of the galvanometer, adjusts the values of the adjustable resistors and capacitors, and calculates Capacitance value and dielectric loss value of the capacitor to be tested.
