Description

Residual current transformer for leakage
current measurement of cable lines. The product
is simple in structure and flexible in
application. According to the cable
specifications used in the main circuit, there
are various core diameters corresponding to it.
The main circuit current includes 63A~2000A. At
the same time, it meets the requirements of
balanced characteristics, and the unbalanced
current output is better than 30mA, 10mA, and
5mA. The product adopts high-quality
high-conductivity magnetic core and advanced
process technology, which can meet the
technical requirements of different precisions
such as 0.2, 0.5, and 1.0, and has high
reliability. This series of products meet the
requirements of GB 14287.2-2014 and GB
13955-2005.
