2. Voltage-output mode for Protecting Voltage Transformers （ZRP-VXX Series）
a. Main Features:
(1)、There’s a settled proportional relation between primary voltage and secondary voltage,
 so that any changes of electric potential in primary load will be 
accurately reacted in the instrument or other devices that in parallel with secondary terminal
(2)、Reliable insulation between primary winding and vice edge winding, winding and shielding
