What does step voltage indicate in the context of electrical safety?

Step voltage indicates a dangerous difference in electrical potential that can occur when a fault condition exists, such as during a lightning strike or electrical surge. When a person stands near an area where ground potential is different, the voltage can vary from one foot to another. This variation in voltage can create a hazardous situation, as it can lead to electric shock if a person bridges that gap between two points of differing electrical potential.

Understanding step voltage is crucial for implementing effective safety measures, especially around trees which can conduct electricity during a storm or when struck by lightning. Thus, recognizing step voltage as a marker of risk is essential in maintaining both personal safety and electrical system integrity during electrical events.
