Introduction
UT225A Low Voltage Transformer Turns Ratio Tester
is extensively applied to
380/220V power system. It can be used to perform fast on-site detection on the
current transformer of metering device, and to measure current and leakage
current in 380/220V power system. Without the need to shut down the power, the
tester enables accurate testing on the actual transformer ratio, phase type and
polarity of current transformer during operation.
UT225A consists of tester, primary current transformer (CT1) and secondary
current transformer (CT2). With small clamp diameter at 8mm, UT225A is suitable
to use in narrow space and environments with concentrated cables, making it a
safe, accurate and portable measurement meter for technicians. The application
of the tester can create significant economic and social benefits for power
enterprises to manage the use of power.
The primary current transformer (CT1) sends testing data via wireless transmission,
with transmission distance of 100 meter.
