thermographic scanning operation
Thermal imaging is also an ideal inspection method for predictive maintenance of electrical systems, including motors, drives, electrical boxes, and distribution system junctions. This method can identify whether the problem is a loose connection, corroded element, or a short or overloaded circuit.
Ultrasonic Detection Testing and Machinery Health Monitoring
Ultrasonic Testing involves the use of an ultrasonic acoustical emissions detector that can capture sound waves above the range of human hearing. It can identify leaks in compressed gas systems, and internal problems in steam traps, valves and pumps.

Fault investigation and trouble shooting
power quality audit
Power Quality Audits identifies power quality issues. This will further help you to address reliability and stability concerns before they actually impact on your facilities performance and more important on bottom line of organization.
Analyzing power quality is an effective way to identify electrical disturbances without having to shut down the system. It can analyze the power quality of your electrical installation by performing measurements during operation to identify disturbances. These disturbances can take many forms ranging from: harmonics, voltage sags/swells/ unbalances, flicker, and transients etc. Our specialized measurement equipment enables us to accurately monitor and record voltage, current, power, harmonics and many other relevant parameters. Short term testing can be used to record the behavior of specific equipment. Long term testing can be used to record ongoing power quality parameters and detect intermittent electrical supply issues.
