36. Saves Lives: How?
All operations behind closed door
1. All switching operations including
emergency manual operations
2. Feeder earthing
3. Rack-in / rack-out operation of
Switching device truck.
4. Not- Emergency manual charging of
VCB operating mechanism.

37. Saves Lives: How?
Front door interlocks
1. Racking of VCB truck from Test to Service position not possible until
the front door is closed and locked.
2. Front door cannot be closed and
locked until the LV control plug is securely connected.
3. Front door cannot be opened until
the VCB is switched OFF and
racked out in Test position.

38. Saves Lives: How?
Partition class: PM
1. Earthed metallic shutters and partitions
ensure partition class PM.
2. Class PM ensures no electric field
in the opened compartment and no
electrical field change in the adjacent
compartments.
3. Thus partition class PM ensures
safe maintenance when the switching
device chamber is opened while
keeping the busbars as well as cables
under charged conditions.

39. Saves Lives: How?
What is an internal arc? It is a high resistance arc fault within the switchgear enclosure due to insulation failure.
What are the effects of an internal arc fault? The fault current passing through the electric arc increases the air temperature inside the faulty compartment. The hot air expands and exerts very high pressure on the compartment walls and doors. If the switchgear is not designed and qualified for an internal arc, the high pressure can rupture the enclosure and endangers the life of persons working near the switchgear.

Correctly secured door and covers do not open.
No fragmentation of the enclosure occurs within the time specified for the test.
Arcing doesn’t cause holes in the accessible sides up to a height of 2 m.
Cotton test indicators do not ignite due to the effect of hot gases.
The enclosure remains connected to its earthing point.
