Embodiment Construction
[0024] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0025] The present invention adopts the voltage frequency conversion technology, through the DSP to control the output module of the power amplifier to generate sine or square wave signals of different frequencies and different voltages, and DC signals of different amplitudes to be sent to the current transformer to be tested, and the voltage values of different loops of the current transformer , Current value, resistance value, frequency value and phase value, etc. are sampled, analyzed and calculated, directly displayed in the form of graphics and data on the man-machine interface interface, and a test report is generated at the same time.
[0026] see figure 1 , is a block diagram of a current transformer comprehensive tester according to the ...
