ELECTRICAL STUDIES AND ARC FLASH EVALUATIONS

Electrical Studies and Arc Flash Analysis

Keystone Engineering Group, Inc. has the knowledge and skills to help your facility comply with OSHA and NFPA 70E to keep your electrical workers safe and protected. We offer the following services:

  • Data collection

  • Short circuit evaluation

  • Overcurrent device coordination

  • Arc Flash incident energy analysis

  • Equipment labelling

  • PPE selection

We use the latest version of SKM Power Tools for Windows and comply with the latest editions of OSHA, NFPA 70E, and IEE 1584

Short Circuit Analysis

We will work with the local electric utility to gather the available fault current and ensure all of the facility's equipment is adequately rated. If any equipment fails, we can recommend replacement equipment that is appropriately rated.

Equipment Labeling

We will provide equipment labels at the conclusion of the study that complies with NFPA 70 and NFPA 70E requirements. This includes the system voltage, available fault current, and available incident energy level.

Arc Flash Analysis

Keystone will utilize the information gathered in the short circuit and overcurrent device coordination to calculate the available incident energy at each piece of equipment as required by NFPA 70E. Incident energy is a measurement of the potential explosive and thermal forces created by an arcing fault that a worker may be subjected to. Increased levels of incident energy may lead to worker injury or even death if the appropriate PPE is not worn. We will identify equipment with elevated incident energy levels and provide PPE recommendations for each piece of equipment in the facility.

Overcurrent Device Coordination

We will evaluate the overcurrent protective devices and their settings for coordination. If devices are found to not coordinate, we will provide recommendations for new settings to provide coordination to the best of the equipment's ability.

Codes & Standards

Keystone's electrical studies comply with the following codes and standards:

  • NFPA 70 (National Electric Code)

  • NFPA 70E (Electrical Safety in the Workplace)

  • IEEE 1584 (The Standard for Arc Flash Studies)

  • IEEE 141, 242, 339, 551, 1015
