IEEE Standard 80, formally titled the “IEEE Guide for Safety in AC Substation Grounding,” stands as one of the most influential technical documents in the history of electrical power engineering. First published in 1961 by the American Institute of Electrical Engineers (AIEE), this standard has guided the safe design of grounding systems for alternating current (AC) substations for more than six decades. The 2013 edition (IEEE Std 80-2013) represents the fifth and most recent major revision of this foundational guide, incorporating decades of practical experience, advances in analytical methods, and critical safety data to ensure that substation grounding systems protect personnel from the hazards of electric shock under fault conditions. This article provides a comprehensive overview of IEEE Std 80-2013, its purpose, key technical provisions, historical development, and practical guidance on how to legitimately obtain the PDF version of the standard.
IEEE 80-2013 is the definitive global benchmark for substation grounding design. It is not a mandatory code in itself, but it is frequently adopted by regulatory bodies (like OSHA in the US) and integrated into utility standards worldwide.

If you are an engineering firm, keeping a legitimate copy of the on every design engineer’s workstation is non-negotiable. It is the difference between a substation that energizes correctly and one that becomes a hazard.
For serious engineering work, academic research, or regulatory compliance, is the only appropriate course of action. IEEE Standard 80, formally titled the “IEEE Guide
Step voltage is the potential difference between two points on the earth's surface separated by a distance of one meter (representing the stride length of an average person), without touching any grounded object. The path of the current is from one foot, up through the lower limbs, and down the other foot into the earth. The tolerable step voltage for a person is defined as:
