General Description

The OTS60SX is a lightweight, semi-automatic, oil dielectric
strength test set. The instrument is suitable for protected field
use and can be powered from a range of mains supplies. The
maximum 60 kV output allows tests to be performed on oil from
a wide variety of electrical installations including transformers,
circuit breakers and other equipment. The operation of the test
set is extremely simple and the results are displayed on a bright
LED display. A selection of vessels enables the instrument to be
configured for a variety of tests.
The semi automatic operation allows all types of testing to be
performed. An automatic one minute timer operates when the
high voltage is paused for Withstand (proof) testing. Oil samples
can also be tested according to breakdown specification by using
a suitable sequence of tests.
The instrument is constructed in a strong, sheet steel case.
Handles are provided for ease of transportation. A pouch is
located on the side of the instrument to contain accessories such
as the power cord, additional electrodes and the spacing gauge.
An optional carrying case incorporates a shoulder strap.
A number of vessels are available suitable for testing to a wide
range of national specifications. Three types of electrode are
available; spherical (IEC type), mushroom (VDE/ASTM D1816)
and cylindrical (ASTM D877). The oil sample can be stirred by a
motor driven impeller available in selected vessels. The vessel is
located in the top of the instrument and covered by a transparent
polycarbonate door with a mesh screen so that the oil breakdown
can be viewed. A safety interlock ensures that the high voltage is
disconnected when the chamber door is opened.
