Case Study II – GSU Transformer Upgrade – Tank Hot Spot
Through simulation, tank hot spot areas are located, their formation is understood, effective solutions to prevent overheating are found and therefore the upgrading of the unit is possible. For all the details click here.
weiterlesenLaminated Transformerboard
Transformerboard is manufactured in accordance to IEC standards, in a single sheet and in a thickness of up to 8 mm. The thickness range can be extended up to 150 mm by laminating Transformerboard T4. In America and Europe Weidmann use liquid adhesives, usually polyester, however depending on the customer specification, may also use casein. […]

Reduce risk and improve reliability with comprehensive testing Gambling with the reliability of your equipment can be very risky business. With substations regularly overloaded and equipment often near the end of its life, electric grid operators are challenged to improve overall system reliability. Without knowing the condition of your critical electrical equipment, making the right […]
weiterlesenCASE STUDY 1: CONVERTER TRANSFORMER LOAD LOSSES
Through simulation, high losses and hot spot areas can be identified at the design stage saving money and time. The actual behavior of transformers in service (considering harmonics of converters) can be studied only by means of simulations. For all the details click here.

The tap changer is one of the most complex parts in a transformer. Out of all the elements of a transformer in operation, it has one of the highest rates of failure occurrence and severity. Careful and regular maintenance is a basic requirement to facilitate trouble-free operation of transformers. The separation of the tap changer […]
weiterlesenToothband and Clackband
A power transformer winding must comply with various requirements under test and guarantee electrical strength in all operating conditions. In addition, the winding must not overheat. A number of concepts are used to avoid the occurrence of overheating. Forming an axial intermediate cooling duct within the winding is a common design principle, especially in the […]

weiterlesenShield Rings
Shield rings, which are also referred to as static rings or metalized screen rings, are placed at both ends of the winding. In most cases they are used to shape the electrical field with an appropriate radius, rather than leaving the sharp edge created by the conductor. The electric surface stress at the edge of […]

Network operators are frequently challenged to increase the reliability of key assets, but at the same time, budgets and available resources are often being reduced. To meet these requirements, new and innovative approaches to asset management are being deployed. Many current transformer maintenance plans involve time-based programs, along with utilizing key individual knowledge of transformer […]
weiterlesenPower vs Space – How to win this battle?
In modern society, electricity is increasingly vital to our daily activities. We need electricity to charge the batteries in our ever-evolving gadgets, to power the amenities of our lives and in the near future, if not already, to power our cars and other means of transportation. Since most of the network infrastructure was put in […]
