14. FIRE PROTECTION FOR TRANSFORMERS
Risk
Main fire risk of overheating and oil ignition
presented by faults (transformer short circuits)
Prevention and detection
 Transformer automatically deactivated when
overheating is detected
 ‘Buchholz Relay’ ensures prompt identification
of required cooling
 Water spray extinguishing system can be
automatically activated by relay
Protection:
 Simultaneous and homogenous distribution of
water prevents fire from spreading further
 Operation can be re-initiated quickly to ensure
a constant power supply to the grid

Maintenance:
System tests can be
performed during normal
operation of transformers

15. FIRE PROTECTION FOR GAS TURBINES
Risk
 Fuel supply in vicinity of burner
 Lubricant circulation system including
turbine bearing in exhaust channel
 Rapid development of open flames
 High thermal loads

17. CO2 SYSTEM - LIFE SAFETY CONSIDERATIONS
Minimum concentration for fire fighting via total flooding is 34% concentration
Exposure to concentration > 17%
(CO2 fire suppressant use) Loss of controlled
activity, unconsciousness, convulsions, coma, deat
h within 1 minute
Exposure to concentration 10 - 15%
Unconsciousness, drowsiness, severe muscle
twitching, and dizziness within several minutes
SYSTEM IN AUTO:
FIRE >>> CO2 RELEASE
PUSH
BUTTON
for
CO2
RELEASE
SYSTEM IN MANUAL:
FIRE >>> ONLY ALARM!
17 / 25
Exposure to concentration 7 - 10%
Unconsciousness, dizziness, headache, visual and
hearing dysfunction, mental depression, shortness
of breath, and sweating within a few minutes to an
hour
Exposure to concentration 4 - 7%
Headache, hearing and visual
disturbances, increased blood pressure, difficulty
breathing, mental depression and tremors
© Minimax 2013

18. CO2 SYSTEM - COMMISSIONING
Commissioning by trained personnel to
meet approval requirements
 Integrity test for each hazard area;
validation of design concentration (&
hold time for total flooding systems)
 Operational checks of all devices,
incl. detection, alarm & activation
 Check for proper labelling of devices
and protected areas, warning anyone
of possible CO2 discharge; signage
must be present to vacate area when
alarm sounds
 Complete inspections of the system
and hazard area to ensure the
system meets specifications and is
appropriate for the type of hazard
18 / 25

19. CO2 SYSTEM - REFILLING HIGH PRESSURE SYSTEM
To be considered
 Without an operational CO2 fire
extinguishing system, your turbines
cannot be restarted
 False alarm can lead to a complete
discharge and may leave you emptyhanded, unless 2nd set of cylinders is
kept on site
Recommendation
 Test with local supplier to validate
guaranteed refill & delivery times
 If not satisfactory (more than 24 hrs),
purchase a spare set of cylinders

20. MURPHY’S LAW - IMPORTANCE OF FULL DISCHARGE
“When things can go wrong, they will …”


Full discharge FAIL; nozzles blocked,
fittings leaked, 1” pipe blocked solid

20 / 25
Installation company certified clean
installation of pipes and fittings with no
excess hemp; all fittings double
checked for tightness; pipes blown out
with compressed air in surges; door
fan test passed the enclosure.
Best practise is one full discharge
every five years, minimum after
installation and/or changes
© Minimax 2013

21. BE CERTAIN AND SAFE
Full discharge FAIL:
Design
34% in 60s
Over 30% after 20min
50kg/min ext. CO2
Integrity test (door fan)
42% in 60s
14kg/min ext. CO2
Actual
24% in 60s
34% not achieved!

23. INTEGRITY – DOOR FAN TEST
Enclosure properties and devices
 Tightness
 Structure
 Penetrations
 Doors and windows (pressure)
 Pressure relief devices
Test Purpose
 Validation and Maintenance
Considerations
 Minimum practise is a scheduled
door fan test after every major
modification to building structure
 AS recommends annual test
