Research on Assembly Automation Technology of New Prefabricated Transformer Prefabricated Transformer

Recent Power Transformer Technology

Power transformers are essential components of substation equipment for the efficient and stable operation of electric power systems. There is demand for transformers with lower price and higher reliability. In addition, depending upon the onsite conditions, such as narrow roads, mountainous areas or highly congested urban areas, harmony with the surrounding environment is required throughout s...

Prefabricated modular structures using ECC technology

Prefabricated modular housing structures have become a promising alternative to site-built structures with equal or higher engineering quality and durability. Major advantages of this technology are fast and cost-efficient construction, reduced labor requirements, and superior quality control due to factory production. The modular design of these prefabricated structures offers the opportunity ...

Prefabricated Elements Case Study

Robotized spraying of prefabricated panels

A robotized manufacturing cell of pre-fabricated GRC (Glass Reinforced Cement) panels for construction industry has been developed by DISAM for the Spanish construction company Dragados, S.A.The main contribution of the developed system is the automatic program~ ming and control of the whole plan. The architect's 3D-drawing of the building facade done on a CAD system serves as input. From the C...

A New Current Transformer Model

This paper presents a current transformer model that is useful on low frequency applications. To describe the iron core magnetic behaviour of the iron core, a hysteresis model is proposed, which is able to generate minor asymmetric loops and remanent flux. The effects of classic eddy current losses and anomalous losses are represented by linear and nonlinear resistors, respectively. The obtaine...
