Product Description
The voltage transformer is a single-phase indoor fully enclosed epoxy resin cast product for voltage and electric energy measurement and relay protection in AC systems with rated frequency of 50Hz or 60Hz and the highest voltage of the equipment is 12kV and below. With fuse protection, and residual voltage winding.
Voltage transformer, also known as instrument transformer, is a voltage conversion device;
The capacity of the voltage transformer is very small, usually only tens to hundreds of volt-ampere;
The primary side voltage of the voltage transformer is the voltage of the network, which is not affected by the secondary load, and its load is constant in most cases.
Secondary side load is mainly instrument, relay coil, their impedance is very large, through the current is very little. If the secondary load is increased indefinitely, the secondary voltage will decrease, resulting in increased measurement errors.
The performance of products is conformed to IEC61869-1:2007, IEC61869-2:2012 commission requirements
