1. Product Introduction
NRHJ Series standard potential transformer is mainly used for factory inspection of instrument transformer and used as measuring standard in metrology department. According to different voltage it can be divided into eight types: 6kV 10kV 35kV 110kV 220kV 500kV 750kV 1000kV; According to different accuracy it can be divided into three types: 0.05% 0.02% 0.01%; According to whether need external high voltage it can be divided into two types: PT with self-boost and PT without self-boost.
2. Product Characteristics
● The potential transformer (110kV 0.01%) with high voltage and high accuracy it can measure the potential transformer which voltage is lower or equal than 110kV and accuracy is lower than 0.1%;
● when the rated secondary voltage is 100V the secondary load is 0.25VA it can completely meet the measuring requirement of PT.
● Easy to move with wheels easy lifting with a handle.
