Fire fighting in electrical installations
•
According to regulations, carbon dioxide (CO
2
) is required to be
used
as extinguishing agent for fighting fire in electrical
installations.
• Carbon dioxide is electrically non conductive and does not leave
residues. It is safe to be used in energized facilities as long as the
minimum distances are maintained. A CO
2
fire extinguisher must be
always available within electrical installations.
•
If, contrary to the regulations, any other extinguishing agent is used
for fire fighting, this may lead to damage at the electrical
installation. Megger disclaims any liability for consequential
damage. Furthermore, when using a powder extinguisher near
high-voltage installations, there is a danger that the operator of the
fire extinguisher will get an electrical shock from a voltage arc-over
(due to the powder dust created).
•
It is essential to observe the safety instruction on the extinguishing
agent.
• Applicable is DIN VDE 0132.
WARNING
Be careful when working with high voltage
Working on high voltage systems and equipment – especially in non-
stationary operation – requires particular care and safety-conscious action
on the part of test personnel. VDE regulations 0104 on setting up and
operating electrical test systems, as well as EN 50191 and national
standards and regulations must be strictly adhered to.
• The System generates a dangerous voltage of up to 10 kV. This is
supplied via a HV connection cable to the test object.
•
The test system may not be operated without supervision.
•
Never fail to use safety equipment or put it out of operation.
•
To prevent dangerous charge accumulation, earth all metal parts in the
vicinity of the high voltage equipment.
• When high voltage is shut off, the cable under test is discharged by an
internal discharge device. This discharge device is designed for a
maximum test object capacity in compliance with the technical data.
This value must not be exceeded. The discharge device may otherwise
become damaged and charge may remain in the test object. The cable
must therefore always be discharged in accordance with the applicable
safety regulations, e.g. discharged using a discharge rod and then be
shorted before the danger zone is accessed.
