1. Description
The CIRCUTOR MI-5500e general purposes insulation tester is a truly
portable equipment, suitable to measure insulation resistances using test
voltages up to 5000 V. It employs high-reliable, state-of-the-art technology
for accurate measurements of high insulation resistances up to
10,000,000 M
Ω with 4 test voltages: 0.5 kV - 1 kV - 2.5 kV - 5 kV.
Insulation of low and medium voltage electrical systems, transformers,
motors, cables, electro-medical equipment and installations, distribution
networks, etc., the measurement are easily performed with great
reliability, using this instrument.
Many experienced technicians consider that insulation measurements are
best performed with analogue instruments, because they get useful
information from the pointer displacement along the time. This equipment
is specially indicated for that people, because it is a true analogue, simple
to use, cost effective, insulation resistance tester.
In order to maximize the operator's safety, this equipment was made
within a plastic cabinet of high breakdown strength. A light indicator warns
about dangerous voltages presence both in the equipment and in the
element under testing, and switches-off automatically when the discharge
process has finished. This equipment has a Guard terminal that allows to
remove the effects of parasitic resistances and surface currents on the
insulation resistances to be measured.
Due to its reduced size and weight, its power autonomy and mechanical
strength, this equipment is suitable for working out in the field, under
severe weather conditions. It is battery powered with an internal,
rechargeable battery. In order to easily carry the cabinet, is rugged,
water-, dust- and sand-resistant.
