The JDT-55 voltage transformer is an electromagnetic oil paper insulated, fully sealed structure product for outdoor use. Used for voltage and energy measurement and relay protection in power systems with a maximum voltage of 63kV and a rated frequency of 50Hz or 60Hz with a neutral point effectively grounded.
The JDT-55 voltage transformer is designed with reliability and low magnetic density, which can reduce the probability of ferromagnetic resonance. The secondary winding separates measurement and protection, and the measurement accuracy can reach 0.2 level, meeting the different requirements of users and the high-precision measurement requirements proposed by the power department
