Specifications

How is ground resistance measured?

Four-Terminal Method: The tester carries out the measurement using four electrodes (the ground electrode under test, the auxiliary current electrode, and the auxiliary voltage electrode).
Current Injection: The tester injects a current of a certain frequency into the ground through the auxiliary current electrode.
Voltage Measurement: The voltage drop caused by the current is measured through the auxiliary voltage electrode.
Resistance Calculation: The ground resistance value is calculated based on the measured current and voltage drop.

Comparative Analysis of 500 kV Prefabricated Substations vs. Conventional Substations

The secondary equipment area of conventional substations uses reinforced concrete or prefabricated steel structures, facing issues like long construction cycles, unreasonable functional zone design, strict environmental assessments, dust, noise, and disturbances. Primary and secondary equipment can only be installed after civil works and decoration, lowering construction efficiency.Prefabricated cabin substations integrate modularity, intelligence, and cost - effectiveness, boasting green, energ

Operational Analysis of Prefabricated Enclosure Substations in Extreme Cold Climate Applications

Under global climate diversity, alpine power construction faces technical and environmental challenges. Extreme climates, complex geology, and long - term low winter temperatures, along with ice, snow, and storms, strain electrical equipment stability and power facility construction (schedule, cost, maintenance).

Underground Power Cable Transmission LinesDirect - buried power cable lines have large ground - distributed capacitance, causing high single - phase - to - ground short - circuit capacitive current. For 10 kV lines, if this current exceeds 10 A, arcs hardly self - extinguish, risking arc overvoltage and endangering line equipment. Arc extinction is thus necessary. With a Dyn - connected main transformer, an arc - suppression coil on the secondary neutral point suffices. For Yd - connected ones,

Failure Analysis and Design Optimization of Conventional Grounding Transformers

I. Core Cause of Damage: Electrodynamic Impact (Complying with GB/T 1094.5 / IEC 60076-5)The direct cause of high-voltage winding end collapse is the instantaneous electrodynamic impact induced by short-circuit current. When a single-phase grounding fault occurs in the system (such as lightning overvoltage, insulation breakdown, etc.), the grounding transformer, as the fault current path, withstands high-amplitude and steep-rise-rate short-circuit currents. According to Ampère's force law
