**-Isolation resistance tester UT513 with a USB connectivity is a professional device able to check a quality of an insulation of installations, transformers, components, ...
Revision technicians are usually the ones, who need to measure an
isolation resistance, but such a device also finds its place in bigger factories
and buildings, where it is convenient to to have a possibility to periodically
(often) measure a status of isolation of for example transformers, motors,
UT513 from company UNI-Trend belongs to a category of
professional devices with wide possibilities of setting, while it still remains
a simplicity of use and an intuitive control. UT513 belongs to a three-member
family of UT51x devices, consisting of
UT511, UT512 a UT513. Devices differ from each other
mainly in the max. voltage for an isolation resistance measurement (1000, 2500,
5000V) and UT512/513 also feature a USB interface for a data transfer to PC
(including a CD with a software).
UT513 is able to store to its memory up to 18 measurements. Isolation resistance
can be also measured with a timer (10 seconds to 15 minutes) and the built-in
timer enables to measure even a polarization index by “one click”.
Polarisation index is maybe more known from optics, but don´t be misleaded :-),
in electronics the polarization index (PI) is a very worth value responding
to a status of an insulation. PI has to be usually in arrange of 2 to 5,
i.e. isolation resistance of tested device after 10 minutes (connected to a
testing high DC voltage) has to be 2 to 5-times higher than at measurement after
the first minute (the reason is a polarization of molecules in insulation).
Function „Compare“ enables to compare measured value of an isolation resistance
with a pre-set value (user-definable) and then the display reads „GOOD“ or „NG“
as - „not good“. Maximum display (with a backlight) value is up to 9999 and here
we can also see an analogue bargraph. As we are already used to at Uni-Trend
equipment, the testing leads are relatively very quality and robust, and also
included are batteries and a mains adapter. Detailed information will provide
you the UT513 user manual.
