The controls and displays of the voltage transformer isolating
device can be seen in figure 4.5.2. Observe the warning signs
(6). Check the switch position indicator (5). The isolating device
can be secured with a padlock (3). Remove the padlock prior to
operation.
Isolating the voltage transformers
To isolate the voltage transformers, pull out the lock knob (2) and
turn the operating lever (1) counter-clockwise as shown on the
direction of rotation indicator (4). Release the lock knob. Turn the
operating lever counter-clockwise until the lock knob engages in
the limit position of the isolating device.
?
When the lock knob engages in the limit position,
the dielectric strength of the isolating device
is ensured.
Secure the isolating device with a padlock in the “OFF” position
(8).
Connecting the voltage transformers
To connect the voltage transformers, pull out the lock knob (2) and
turn the operating lever (1) clockwise as shown on the direction of
rotation indicator (4). Release the lock knob. Turn the operating lever
clockwise until the lock knob engages in the limit position of the isolat-
ing device.
?
When the lock knob engages in the limit position, the
current carrying capacity of the isolating
device is ensured.
Secure the isolating device with a padlock in the “ON” position (7).
