Technical features
Description and functions Measure Checking test value
Oil level (Float)
The device indicates any gas evolvement or oil level variation.
- Slight oil level variation or any insignicant gas evolvement is denoted by the
oat position between “MIN” & “MAX” on the display.
- At major oil variation level or gas evolvement the oat stops at “MIN” and
opens/closes the alarm circuit.
- Any accumulated gas can be drawn off by the valve provided.
Max 150 cm3Locate the magnet close to the oat
(between MAX and MIN). Drawn it
downwards until it reaches “MIN”.
To reset the oat to its correct
position draw the magnet upwards
and detach.
Pressure (Pressure switch)
This feature measures the internal pressure of transformer. The normal level is
to be set by the user according to the transformer manufacturer’s instructions.
When pressure exceeds a pre set level the alarm circuit is triggered by a change
over contact.
100 mbar to
500 mbar
With the internal pressure at least
100mbar set the adjusting knob of the
pressure switch to minimum.
Temperature
“T2” Thermostat switch (Alarm)
The feature measures the internal oil temperature of the transformer.
The normal operating value is to be set by the user according to the transformer
manufacturers instructions. At a pre set temperature the alarm circuit is triggered
by a change over contact (T2).
30°C to 120°C Open the rear cover using both hands,
do not lever at one side only.
The adjustment knob of the alarm
switch “T2” should be set to the
minimum value.
“T1” Thermostat switch (Stop)
The feature measures the internal oil temperature of the transformer.
The normal operating value is to be set by the user according to the transformer
manufacturers instructions. At a pre set temperature the stop circuit is triggered
by a change over contact (T1).
30°C to 120°C The adjustment knob of the stop
switch “T1” should be set to zero.
The adjustment knob of the stop
switch “T1” should be set to the
minimum value.
Thermometer
The device measures the internal temperature of the transformer, which shall
be visualized outside the device through the protection window.
The thermometer is equipped with a drag pointer.
30°C to 160°C The protection window is to be
unscrewed so that the pointer shall
be set to the minimum values.
