Michigan Switchgear will provide specific information to help
companies prevent or minimize exposure to all widely recognized
electrical related hazards. Safety practices, such as those
recommended by NFPA 70E, help minimize maintenance techs risks
of burns, blindness, electrocution, electric shock and disabling
injuries. Reducing costs and reducing risks.
Arc Flash Analysis
The following is a recommended list of
technical information needed to perform a coordination study of
customers electrical system and ultimately to perform an Arc
Flash Study for personal protection. This is a generic list and
will cover the majority of information needed; however, since
very few customers electrical systems are the same additional
information will need to be collected when the study is
started. Most important is an accurate one-line diagram. The
more information supplied your analysis cost will be reduced.
A tabulated list follows:
- One line diagram
- Utility supply voltages and configurations
- Primary fuse data
- Primary breaker nameplate data with protective relays
settings
- Transformer nameplate data including transformer
impedance (Z)
- Transformer secondary breaker (main) nameplate data with
relay settings
- Secondary buss voltages and current ratings
- All secondary breaker (feeder) nameplate data with
protective relay or trip device settings
- All main and feeder cable data including lengths
- All feeder fuse data
- Motor data
As stated earlier the above list will cover
most information needed and some items may not be used on some
customer’s electrical systems.
If the customer has had coordination study
completed sometime in the past, this is an excellent source of
information for all this information
