How to test the insulation resistance of cable ?
To meet the operational demands of the power system, we must prioritize insulation performance and conduct insulation tests. Before use or upon finalizing a product design, standard testing methods must be employed to ensure that the insulation properties of wires and cables meet design and usage requirements.
How AC Resonance Testing Enhances GIS Reliability and Longevity
AC resonance test system helps extend the lifespan of GIS components, allowing operators to maximize the return on investment in this critical electrical infrastructure. By incorporating resonance testing into their maintenance strategies, utilities and industrial operators can significantly improve the operational efficiency and durability of their GIS systems.
Why AC Resonance Testing is Essential for Transformers
AC resonance testing is an indispensable tool throughout the transformer life cycle—from factory acceptance and commissioning to routine maintenance and troubleshooting
Vacuum switch vacuum degree tester
Vacuum switch vacuum degree tester utilizes an innovative excitation coil and employs the magnetron discharge method to evaluate the vacuum degree of the arc extinguishing chamber without requiring disassembly.
What is the difference between tan delta test and megger test?
Tan delta testing, also known as dissipation factor (PF) testing, or loss angle testing or dielectric dissipation factor（DDF) , is a diagnostic method used to measure dielectric loss/dissipation factor(tgδ) and capacitance (Cx) and evaluate the insulation condition of electrical equipment, such as cables, transformers, capacitors, and rotating machines.
