3. INTRODUCTION
The
OT-60
range is automatic equipment especially designed to test the disruptive
voltage of isolating oils in new or used transformers, cables with oil, automatic switches,
capacitors, etc.
The disruptive voltage is not a basic property of the oil, but it indicates us the degree
of contamination of this oil (water, solid materials in suspension), allowing us to decide on
the possibility of carrying out a treatment of drying and filtration, or replacing the oil.
The method that the OT-60 uses can be applied to oils of nominal viscosity of up to
350 mm
2
/s at 40ºC, according to IEC-156 standard.
The
OT-60
is supplied with a complete series of protectors making it highly protected
and reliable.
It is easy to handle, all buttons or illuminated switches are on the front control panel;
there is also an audible signal each time a key is pressed or when the oil sample is
perforated.
The test cell is especially designed to easily change the electrodes in accordance
with the different standards in operation, the easy insertion into the registering transformer
terminals and for its complete cleaning.
The equipment also has a magnetic stirrer to completely mix the oil to be tested. The
moving part ot the stirrer is a small teflon coated magnet.
