SF6 Gas recycling – environmental friendly
SF6 gas is an insulating medium gas widely used in the power industry and industrial sector, but it has a high greenhouse effect and is one of the main causes of global warming. In order to reduce the impact of SF6 gas on the environment, recycling and reusing SF6 gas has become a consensus in th...Read more -
Exploring SF6/N2 mixed gas : advantages, applications, and analysis
SF6/N2 mixed gas is a widely used insulation medium in the power industry. In traditional GIS (gas insulated switchgear), SF6 gas has always been used as an insulation medium, but due to its high global warming potential, SF6 is gradually receiving attention. In contrast, SF6/N2 gas mixtures have...Read more -
What causes the current transformer to burn out
HV HIPOT GDHG-306D CT/PT Analyzer The first reason is that the secondary side of the current transformer is caused by an open circuit due to weak wiring In the process of using a current transformer, if the secondary side opens due to wire disconnection, the current will be equal to ze...Read more -

How to test whether the motor winding is grounded
When the windings of the motor short circuit to the ground, short circuit to each other or open the circuit (that is, the winding wire breaks), the motor will fail. The wires in the winding use an insulating covering as an isolation barrier. If the insulation layer of the winding is worn near the...Read more -
What are the measurement methods of using a high voltage generator
High voltage generator alias direct high voltage generator or DC high voltage generator, it is specially used to detect the electrical insulation strength and leakage current of power devices. Generally, the use of high voltage generators is to carry out DC voltage withstand test on zinc oxide ar...Read more -
Ground fault Circuit breaker test troubleshooting
Troubleshooting ground fault circuit interrupts or GFI breakers is simple. Troubleshooting the circuit itself can be time-consuming. The GFI circuit breaker design has a test button integrated into the circuit breaker itself. Pressing the test button should trip the circuit breaker. On a GFI type...Read more -
Causes of partial discharge of high voltage switchgear
During the operation of power equipment, when partial discharge occurs, various charged particles such as electrons, positive and negative ions, stimulated by the electric field, generally have more energy than the bond energy of the polymer. These charged particles strike the walls of the dielec...Read more -
