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.
AC resonance testing is an indispensable tool throughout the transformer life cycle—from factory acceptance and commissioning to routine maintenance and troubleshooting
Transformers are essential in power systems due to their ability
A battery converts chemical energy into electrical energy by creating a potential difference between two electrodes (anode and cathode) through a chemical reaction.
When a battery is discharged, electrons flow from the anode to the cathode while ions in the electrolyte move to maintain charge balance; when it is charged, the process is reversed.
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.
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.
Sweep Frequency Response Analysis (SFRA) test is an important measurement method used to assess the mechanical and electrical integrity of power transformers. It tests the mechanical integrity of transformer cores, windings, and press frames by measuring the voltage transfer function over a wide frequency range. Each electrical network has a unique frequency response called a frequency response fingerprint.
The secondary injection test for protection relays is a common testing method used to evaluate the performance and functionality of protective relays in electrical systems.
There are some tests for insulation oil testing include Breakdown voltage (BDV)test, water content test, acidity test, Dielectric Dissipation Factor test, Interfacial Tension test, Flash Point test, Viscosity test, Relative Density Test, Furan Analysis , Dissolved Gas Analysis (DGA)ect.
This article will talk about the methods of cable testing .The cable testing focused on insulation layer and the leakage , withstand voltage , dielectric loss and partial discharge characteristics of cable insulation
