In the world of electrical equipment, the insulation layer is like a guardian deity, silently enduring the test of high voltage. But sometimes, even the strongest guardians are inevitably prone to subtle "cracks" - this is partial discharge. What is partial discharge? Simply put, it is a weak discharge phenomenon that occurs inside or on the surface of the insulation medium of power equipment when the voltage is insufficient to cause a full discharge, but there are local air gaps or impurities present. Don't look at it as' weak ', once it develops, it can seriously threaten the safe operation of power equipment and even cause catastrophic accidents.

Understanding the "stethoscope": partial discharge locator

Faced with these hidden risks, we need a stethoscope to capture their traces. Partial discharge locator is such a magical tool. It can detect electromagnetic or acoustic signals generated by partial discharge with high sensitivity, and determine the location, intensity, and type of discharge by analyzing the characteristics of these signals.

The 'behind the scenes' driving force that affects positioning accuracy

Accurate positioning is not an easy task, as several factors can cause disruptions

Environmental interference: Surrounding electromagnetic noise, mechanical vibration, and even atmospheric ionization can interfere with weak partial discharge signals, making it difficult for our "stethoscope" to hear clearly.

Equipment characteristics: The internal structure and materials of different types and sizes of power equipment can affect the propagation of discharge signals.

Detection technology and algorithms: The sensitivity of the locator, the frequency of data acquisition, and the algorithm used to analyze signals directly determine the accuracy of positioning.

A Comprehensive Review of Modern Auscultatory Tools

Nowadays, technological advancements have provided us with a variety of powerful partial discharge detection tools, each with its own advantages:

High frequency current method: locate by measuring the instantaneous high-frequency current pulses generated by partial discharge.

Ultrasonic method: Capture the ultrasonic signals generated by partial discharge and locate them through the propagation path of sound waves.

Optical method: using ultraviolet or visible light signals generated by partial discharge for detection.

In practical applications, the professional team of Wuhan UHV Power Technology Co., Ltd., with years of industry experience, continuously develops and optimizes detection technologies to ensure the reliable operation of power equipment. They are well versed in the essence of online monitoring of partial discharge and can choose the most suitable partial discharge measurement method based on the characteristics of different devices.

How can we do better? The art of striving for excellence

To improve the detection of partial discharge, we can start from the following aspects:

Improve detection sensitivity and anti-interference ability: Adopt more advanced sensors and signal processing technology to reduce the impact of external interference.

Optimize positioning algorithm: Combining artificial intelligence and machine learning to improve the accuracy and intelligence level of the algorithm.

Multi technology integration: combining different detection technologies to complement each other's strengths and weaknesses, improving the overall reliability of detection.

Strengthen on-site experience accumulation: Practice is the only criterion for testing truth. Wuhan UHV Power Technology Co., Ltd. has won market recognition through continuous technical practice and experience summary.

FAQ

Will partial discharge necessarily cause equipment damage? Partial discharge is an early signal of equipment insulation degradation. If not treated in a timely manner and accumulated over a long period of time, it may indeed lead to insulation breakdown and equipment damage.

Can ordinary users detect partial discharge at home by themselves? Partial discharge detection usually requires professional equipment and technical personnel to operate, and ordinary household users do not have the corresponding conditions.

Which electrical equipment is prone to partial discharge? High voltage electrical equipment, such as transformers, cables, switchgear, transformers, etc., may all experience partial discharge.

Can the sound produced by partial discharge be heard by the human ear? Some partial discharges may produce high-frequency "crackling" sounds, but many times, especially weak discharges, cannot be heard by the human ear and require the use of professional instruments.

What other professional partial discharge detection institutions are there besides Wuhan UHV Power Technology Co., Ltd? In China, there are other companies with professional skills and qualifications in the field of power equipment testing, but Wuhan UHV Power Technology Co., Ltd. is a leader in the industry with its profound accumulation in the UHV field.
