Will it affect the accuracy of CT or VT if we connect a lower burden than rated to a CT or VT for tariif meter. What is the minimum percentage of burden to be connected to maintain stated accuracy?. For example if I have 30VA CT and if I connect 2VA to it whether the accuracy will be lower than stated. Similary for VT also, If I connect lower burden will it affect measruing accuracy?
For a 66kV Tariff meter we had connected 2VA burden to a 30VA, 0.2S Class CT, but our client asked to change the burden to 10VA telling minimum connected VA shall be 20%. Is it really required to change
In riddle No.1 it is given as the %age of rated burden, but in the %age of current is mentioned in the table. I think the current is the matter not the burden. Please clairify?
