Description
The Mobile Power Test Intelligent Integrated System — Power Test Vehicle is a professional on-site tool for high-voltage power systems, focusing on "intelligent integration" and "mobile operation". It integrates insulation testing, withstand voltage testing, cable fault location and data analysis, with a stable vehicle platform that resists vibration and adapts to complex sites like substations. Adopting modular intelligent design, it has AI-assisted functions for automatic equipment identification and report generation, plus an electric lifting platform. Suitable for 10kV–220kV equipment (transformers, cables, etc.), it solves traditional fixed equipment’s site/mobility limits, supporting grid maintenance.
System Features
The system is a modern power testing equipment integrating mobility, informatization, and intelligence through systematic integration on a motor vehicle chassis. It features fixed-position management, rapid deployment, easy on-site setup without lifting equipment, reduced testing labor intensity, and improved work efficiency.
A single vehicle can independently perform partial discharge tests or series resonance withstand voltage tests.
The test platform is automatically deployed via a "one-click" hydraulic device, eliminating on-site lifting needs. The equipment deploys stably and occupies a small area.
Main circuit wires are fixedly connected, eliminating repetitive wiring work.
Humanized operating space with control switches grouped by function for easy identification and operation.
Fiber optic or wireless communication between power and control modules ensures reliability.
Using an enclosed container as the carrier, it offers excellent resistance to rain, moisture, and sand. During use, it can automatically deploy to a testing state to meet the insulation distance required for testing.
All external test wires needed for on-board equipment are centralized for convenient test wiring.
All auxiliary equipment required for testing is integrated, eliminating the need for additional preparation.

5 Common Transmission Line Faults and Effective Prevention Methods1. OverviewA transmission line fault is a sudden power interruption caused by various factors. To restore supply and prevent recurrence, operators must first locate the fault point, identify the type, determine the cause, and implement repairs.The most common faults include: Lightning strikes Ice buildup (icing) Wind deviation (wind sway) Bird-related issues Pollution flashover External damageUnderstanding these faults and their prevention is critical for grid reliability.2.

Transmission LineIn transmission lines, a "π" connection involves breaking the original line from Substation A to Substation B and inserting Substation C, forming a "π" configuration. After the "π" connection, the original single line is divided into two independent transmission lines. Following the "π" connection, Substations B and C may both be powered by Substation A (in this case, Substation C receives power via a feeder from Substation B's busbar, or possibly from another voltage point within Substation B);Encyclopedia09/04/2025 -
What are the principles of forced re-energization of transmission lines?Principles of Forced Re-energization of Transmission LinesRegulations for Forced Re-energization of Transmission Lines Correctly select the forced re-energization end of the line. If necessary, change the connection configuration before forced re-energization, taking into account the reduction of short-circuit capacity and its impact on grid stability. There must be a transformer with its neutral point directly grounded on the busbar at the forced re-energization end. Pay attention to the impactEdwiin09/04/2025 -
Analysis of Accident Handling in Transmission LinesAnalysis of Transmission Line Fault HandlingAs a fundamental component of the power grid, transmission lines are widely distributed and numerous, often exposed to diverse geographical and climatic conditions, making them highly susceptible to faults. Common causes include overvoltage, pollution flashover, insulation damage, tree encroachment, and external damage. Line tripping is one of the most frequent faults in power plant and substation operations, with fault types including single-phase-to-Leon09/04/2025
