Product Description
The function of the Current Transformer and Votage Transformer is
to reduce the AC voltage and the large current in proportion to the
value that can be directly measured by the instrument, so as to
facilitate the direct measurement by the instrument, and at the
same time to provide power for relay protection and automatic
devices.Power system with high voltage, large current transformer
is the power of information transmission to the low voltage, low
current measurement of secondary side, measuring instrument and a
special transformer relay protection and automatic device, and the
secondary system is a system of contact element, one of the primary
winding is connected to the electricity grid, secondary winding
respectively with measuring instrument, such as protective device
connected to each other.The transformer can measure the voltage,
current and electric energy of the primary system in coordination
with the measuring instrument and measuring device.Together with
relay protection and automatic devices, it can constitute
electrical protection and automatic control for various faults of
the power grid.The performance of the transformer has a direct
impact on the accuracy of the measurement and measurement of the
power system and the reliability of the operation of the relay
protection device.
