What is conductor gall?

Conductor gall refers to a large-amplitude, low-frequency self-excited oscillation that occurs in transmission lines under icing and specific combinations of wind speed and direction. It is completely different from ordinary breeze vibration: its amplitude can reach several meters or even more than ten meters, and its shape sometimes flutters up and down, sometimes sways left and right, and in severe cases presents an elliptical trajectory, so it is known as the "cancer" of transmission lines in the industry.

The three major factors contributing to gall are all indispensable:

1. Uneven icing: Non-circular cross-section ice layers such as crescent-shaped and airfoil-shaped form on the conductor surface, changing its aerodynamic characteristics;

2. Stable lateral wind: With wind speed between 5~20m/s and an angle of about 45°~90° between the wind direction and the line, it generates lift and torque, forming a negative damping effect;

3. Line's own parameters: Large span, low tension, and insufficient damping, so that the energy input from the outside cannot be dissipated.

When these three conditions are met simultaneously, gall may break out at any time.

How can we "see" the dance in the wind and predict risks in advance?

TLKS-PMG-WD Transmission Line Gall Perception System provides the answer.

I. How do we "see" the dance in the wind?

TLKS-PMG-WD Transmission Line Gall Perception System is an intelligent terminal specially designed to capture conductor gall. It is like a tireless "motion capture expert", using sensors instead of human eyes and algorithms instead of experience, so that every gall leaves a traceable data trajectory.

II. Three core capabilities

1. Motion restoration: Not only tells you that it exists, but also tells you how it moves
Traditional methods can only confirm that "the line is moving"; this system can clarify "how it moves". Through multi-sensor fusion, it synchronously obtains data such as displacement, acceleration, frequency, and amplitude, collects more than 400 points at a time, with a comprehensive error of less than 10%, and completely draws the three-dimensional trajectory of the conductor - how large the up-and-down swing amplitude, how much the left-right offset, and the vibration speed are all clear at a glance.

2. Risk prediction: Not only looks at the present, but also at the trend
Gall rarely occurs in isolation and is often linked to meteorology. The device has a built-in micro-meteorological module that simultaneously measures wind speed, wind direction, temperature, and humidity, establishing a correlation model between gall and weather. When the wind speed approaches the critical value and the wind direction forms a dangerous angle with the conductor, the system can estimate the gall probability and risk level in advance - the early warning is issued before the gall occurs.

3. Closed-loop disposal: The alarm is not the end, but on-site verification is needed
While issuing the early warning, the device supports high-definition video recording and AI recognition verification. After the operation and maintenance personnel receive the notification via mobile phone or computer, they can immediately access the on-site footage to intuitively confirm whether gall has actually occurred, avoiding false alarms and missed alarms. From perception, early warning to verification and disposal, a closed loop is completed.

III. "Rugged" design adapted to harsh environments

IV. From "invisible" to "predictable"

In the past, gall management relied on post-facto repairs, which was costly. Now, the TLKS-PMG-WD Transmission Line Gall Perception System uses multi-source data fusion and intelligent analysis to turn unpredictable "air dances" into a set of quantifiable, analyzable, and traceable data streams. It not only provides early warnings, but also offers scientific basis for gall management and line design optimization.

V. Final note

The wind still blows, and the lines still move. But with the TLKS-PMG-WD Transmission Line Gall Perception System, we no longer have to wait passively, but can take the initiative to control. In today's era of accelerated construction of new power systems, making every gall traceable and every risk detected in advance - this may be the most practical annotation of smart power grids.
