Yesterday we received high praise from customer about our GDVA-405 automatic CT PT analyzer! The customer said: The performance of our GDVA-405 Automatic CT PT is very good! And it will show the connection for performing the test also. It will be more convenient for customers when operation.
Meanwhile, the customer also has a question about the excitation curve: "For the graph,we need to explore if there is option to set plotted graph for Vkp can be plotted in bode plot scale or not. And if this is graph plotted in bode plot scale I think the graph will not this curvy."
According to the customer's question, we learned from the technical department: The customer chose the quick test mode, and the step size of the pressurization is larger. We recommend that customers use the standard mode or connect the excitation module to the power output port. Both of these methods can improve the voltage resolution and the curve will be smooth.
The customer is very satisfied with our response and will take our advice in next test work.
GDVA-405 Automatic CT PT Analyzer is designed for automatic testing of protection and metering CT/PT (220V~500KV,capacity ≥2.5VA), suitable for laboratory and field testing. This source generates AC of 0-180V and 0.001-5A current to sample CT. The accuracy is 0.02%(Typical),0.1%(Guarantee).
