Measurement of Touch and Step Voltage for Industrial Electrical Safety
Protects people and assets with accurate measurements that comply with international standards.
Measurement of touch voltage and step voltage
What is Touch and Step Voltage Measurement?
Touch and step voltages refer to the potential differences a person may experience when touching a metal object or walking on the ground surrounded by an electrical system. These voltages can pose a risk of electrocution or serious injury if they exceed safe limits.
This service makes it possible to measure these voltages in order to design, correct, or validate grounding systems and ensure safety in:
Electric substations
Industrial plants
Maintenance areas
Areas with medium- and high-voltage infrastructure
What Do We Measure, and Why Is It Important?
Touch Voltage:
Potential difference between an accessible structure and the ground where an operator stands.
Step Voltage:
Potential difference between two points on the ground separated by the length of a step (≈1 m).
Ground resistance (Rt):
Evalúa la eficacia del sistema de tierra.
Ground electrode resistance:
Identify areas at risk of high stress.
Impact on security and compliance:
Prevent electric shock accidents
Reduces operational risks
Ensures compliance with safety standards
Supports electrical maintenance decisions
