Lightning protection system, enhance building resilience to lightning strike. More architects are specifying them because climate change is increasing the frequency of lightning strikes, and the growing use of electronic devices in buildings make them vulnerable to lightning surges.
Thermal / Infrared testing, or infrared thermography, is used to measure or map surface temperatures based on the infrared radiation given off by an object as heat flows through, to or from that object.
We can use the temperature to predict or diagnose a potential failure. This temperature is directly related to the materials, the thermal energy level and heat transfer rate.
Thermal imaging can be used to detect corrosion damage, delamination, disbonds, voids, inclusions.
Honey Comb Electrical Service Introduction to Infrared Thermography
Earth Measurement is very critical for facilities, earth resistance tests power distribution lines, electrical appliances and it also has measurement for earth voltage ranges.
Fault occurs at a tower or substation, the current will enter the earth. Based on the distribution of varying resistivity in the soil typically, a horizontally layered soil is assumed a corresponding voltage distribution will occur.
Ground Potential Rise (GPR) or Earth Potential Rise (EPR) is a phenomenon that occurs when large amounts of voltage and current enter the earth.
It is generally caused when lightning strikes at electrical power equipment or when there is an electrical fault in the electrical equipment such as transformer or switchgear. When currents of large magnitude enter the earth from a grounding system, not only will the grounding system rise in electrical potential, but so will the surrounding soil as well.
The voltages produced by a Ground Potential Rise or Earth Potential Rise event can be very hazardous to the personnel working in the vicinity.
Licensed in Electrical Worker LEW / Professional Engineer Services, we provides Electrical Equipment Tests and Measurements and Electrical Consultation.
We also provide equipment rentals, we have 2 types of equipment KEW 4106 and Flir E8. KEW 4106 for measuring Earth Measurement and Flir E8 is use for infrared thermography.
