Laboratory for testing grounding systems, lightning protection and electrical installations

History

Testing of grounding systems, lightning protection, and electrical installations has been going on for more than 60 years at power production, transmission, and distribution facilities of all voltage levels. Standards governing public safety and workplace safety and health are monitored by frequent inspections and acceptance testing.

Primary activity

Testing the grounding system in electric power facilities with a nominal voltage greater than 1000 V

Measuring the earthing system's impedance using the method of measuring current and voltage
Measurement of touch voltage and step voltage using the current and voltage measurement method
Checking the electrical facility's grounding for continuity
Using the Wenner method to measure soil specific resistance

Tests on low-voltage electrical installations

Measuring the insulating resistance of electrical installations
Conductor continuity test (potential equalization) using electrical resistance
Checking the condition of the power supply's automatic interruption protection by measuring the fault loop's resistance
Checking the differential current protection device's functionality while automatically turning off the power supply to test the protective conditions
Assessment of protective conditions by automatic power interruption by measuring the overall resistance of the grounding device

Lightning protection system testing

Checking the earthing system, the down conductor system, and the receiving system for continuity
Measuring the propagation resistance of conductors used in lightning arresters
Potential equalization test
