Removing the voltage transformers

DANGER

Hazardous voltage.
Will cause death, serious injury and property damage.

Always observe the Five Safety Rules:
➭ Isolate.
➭ Secure against reclosing.
➭ Verify safe isolation from supply.
➭ Earth and short-circuit.
➭ Cover or barrier adjacent live parts.

DANGER

Hazardous voltage
Can cause death, injury or considerable property damage.

The metal coating on the outside of voltage transformers is connected to earth potential.
If the metal coating is damaged, the voltage transformer is not safe-to-touch anymore.
➭ Do not damage the metal coating of voltage transformers.

WARNING

Internal arcing and explosion hazard
If a voltage transformer is short-circuited, there will be a considerable current flow.
This considerable current flow implies the risk of internal arcing, and the voltage
transformer can explode and produce a fire. Death, serious injury and considerable
property damage can be the consequence.

➭ Never short-circuit voltage transformers on the secondary side.
➭ Check the voltage transformer circuits from the voltage transformer to the secondary fuse

or short-circuit protective device for short circuits.

➭ Check correct operation of the existing protective devices in the voltage transformer

secondary circuit.

NOTICE

Damage to parts of the switchgear
Non-observance of the following instructions can damage sensitive parts of the
switchgear while working at the busbars and busbar housings.

➭ Position and align the busbars and busbar supports carefully.
➭ While working at the busbars or the busbar housings, prop up only on the aluminum

housings and the frame.

➭ Do not prop up on sensitive parts of the switchgear like gas pipes, bursting discs, shafts,

etc.

NOTICE

Considerable property damage
During the high-voltage test, connected non-disconnectable inductive voltage
transformers may be damaged.

➭ Remove any already mounted non-disconnectable inductive busbar voltage transformers

which are not suitable at least for tests at 80% values according to IEC 62271-200.

➭ Close the transformer bushings in a surge-proof way.
➭ Check the SF6 gas filling (see page 60, "Checking the SF

6

gas pressure").

➭ Switch the disconnecting facility for panels with disconnectable voltage transformers to

OPEN position before performing the high-voltage test.
