Arc Flash Hazard Calculator
ArcCalc calculates the incident
energy and arc flash boundary for any point in a power system.
Minimum and maximum arcing short
circuit currents are calculated using broad tolerances to provide
conservative results with estimated system data. ArcCalc saves time by
automatically determining trip times from the protective device
settings. Incident energy, arc flash boundaries and PPE are calculated
following the NFPA 70E and IEEE 1584
- 1. Calculator-style interface makes complex
calculations easy to understand.
- 2. Provide a safer working environment by
specifying the proper level of PPE. Wearing inadequate clothing is
dangerous for obvious reasons, but wearing too
much clothing is dangerous due to limited mobility and visibility.
- 3. Design safer power systems while insuring
compliance with NEC 110.16, OSHA, NFPA 70E and IEEE 1584 standards.
- 4. Evaluate alternatives quickly and easily to
understand the possible hazard.
- 5. Improve safety margins with user-definable
arcing fault tolerances.
- 6. Improve safety margins with user-definable
fault source and impedance tolerances.
- 7. Save time by automatically generating arc
flash labels and work permits.
- 8. Avoid potential fines, lost productivity,
and increased insurance and litigation costs.
- Simple calculator-style interface.
- Network one-line includes user-definable fault
source, cable, transformer and motor.
- Protection can be located anywhere on the
one-line relative to the equipment bus.
- Intelligent default data for fault sources,
transformers, cables and motors.
- Intelligent default data for arcing fault
variables including bus gap and working distance.
- Comprehensive library with thousands of
validated protective device trip characteristics.
- One-line display annotated with input data,
short circuit values, trip times and flash hazard.
- Bus and branch arcing fault values are
calculated, and trip times are automatically determined from the
protective device settings.
- Arc Flash labels are automatically produced to
comply with NEC 110.16 labeling requirements and can be printed in any
- Create custom labels in any size with
user-defined logos, text, comments, field placement,
and local language support.
- Option to follow the NFPA 70E or IEEE 1584
- Option to report in English or Metric units.
- Option to adjust arcing fault tolerance.
- Allows representation of differential,
zone-interlocking, photo-sensing and other special instantaneous
- Induction motors can be included for a
- Maximum arc duration may be specified for
situations with long trip times.
