Questions regarding the burnout of the PT in the 10KV system
Thread Content
Our company is a chemical manufacturing enterprise, and the PTs in our 10KV system have been damaged several times; after analysis, resonance is suspected to be the cause. Who knows what the reason is? Please give me some advice.
Why hasn’t anyone replied to my question? Did I not explain the question clearly? If anyone has questions, feel free to ask. Looking forward eagerly!
Does your company’s chemical processing equipment make use of many devices that generate harmonics, such as rectifiers and frequency converters? Also, what is the condition of the power supply lines – are there any harmonics present? If your company’s PTs have been damaged, do the high-voltage devices lack harmonic suppression devices or are these devices not functioning properly? It is recommended to replace them or add such devices.
You can also hire a professional company to test the harmonic levels in your company’s power grid
Some devices generate harmonics; these can be detected using instruments, or the devices can be shut down
