⚡ IEEE 80 (Tolerable Touch Voltage E_touch & Step Voltage E_step Limits Volts)

IEEE 80 Touch & Step Voltage Limits Calculator

Calculate human tolerable touch and step voltage threshold limits to prevent ventricular fibrillation during substation ground faults under IEEE 80-2013: calculate maximum allowable mesh and step potentials (Volts based on 50 kg or 70 kg body weight models, fault clearing duration t_s 0.1 to 1.0s, and surface rock resistivity), and safety compliance margins.
