Thermography
This testing helps our customers identify internal arcing, bad electrical contacts, hot spots, partial discharge, or overheating the conductors.
Ultrasound
This testing can identify the surface partial discharge, which is the corona, tracking & arcing. With the help of magnetic contact probe sensors, mechanical vibration can also be determined.
Internal Partial Discharge (TEV)
TEVs are the current convenient phenomenon for measuring and detecting internal & surface partial discharges as they can be detected without making any electrical connection or removing any panels.
SF6 Leak Test
This testing is for locating and quantifying the SF6 gas leakage rate at the switchgear.
Trip Test (On-Line Timing)
This type of test is performed to test the breaker in the energized state so that the performance of the first trip can be analyzed. The current profile allows the diagnosis of potential defects in the circuit breaker mechanism.
SF6 Analysis
This type of testing checks the reliability of SF6 switchgear in the form of density or gas pressure in the sealed compartments (moisture content, purity & density).
CB Timing Test
This type of testing is crucial in ensuring the readiness of the breaker to perform its duty after the maintenance.
Insulation Resistance
This type of testing indicates the relative quality of the insulation system of a piece of equipment.
Contact Resistance
This type of testing is primarily to verify that the electrical connections are made correctly and can detect problems such as loose connections, adequate tension on bolted joints, eroded contact surfaces, and contaminated/corroded contacts.
Pressure Test
This type of testing is to access the ability of switchgear or objects under test to withstand voltages in excess of its rated voltage at power frequency for 1 minute. This activity is to examine the ability of the object to withstand the voltage.
SF6 Laboratory Test
This type of testing is to verify the quality of SF6 gas, which must be constantly maintained as the contaminants can negatively impact the dielectric and arc quenching properties of the SF6 gas inside the GIS equipment.
Vacuum Check
This type of testing is primarily to verify that the electrical connections are made correctly and can detect problems such as loose connections, adequate tension on bolted joints, eroded contact surfaces, and contaminated/corroded contacts.
Advanced Solutions
This type of testing is to verify the quality of SF6 gas, which must be constantly maintained as the contaminants can negatively impact the dielectric and arc quenching properties of the SF6 gas inside the GIS equipment.
