NLTC vs. OLTC: The Great Transformer Tap Changer Showdown!
Hey there, transformer enthusiasts! Ever wondered what makes your power transformer tick? Well, today, we’re diving into the fascinating world of tap changers—those unsung heroes that keep y...Read more -
Benefits between AL and CU winding material
Conductivity: Copper has higher electrical conductivity compared to aluminum. This means that copper windings typically have lower electrical resistance, resulting in lower power losses and better efficiency in electrical equipment. Aluminum has lower conductivity compared to copper, which may re...Read more -
Transformer Efficiency-2016 U.S. Department of Energy(DOE)
New U.S. Department of Energy (DOE) efficiency standards for distribution transformers, which went into effect on January 1, 2016, require an increase in the electrical efficiency of critical equipment that distributes power. The changes impact transformer designs and co...Read more -
Transformer Surge Arrester: A Vital Protection Device
A transformer surge arrester is a crucial device designed to protect transformers and other electrical equipment from the damaging effects of overvoltages, such as those caused by lightning strikes or switching operations in the power grid. These overvoltages can lead to insulation failure, equip...Read more -
The Maintenance of Oil-immersed Transformer & the Note Concerning Oil Sealing
The transformer oil is contained within the oil tank, and during assembly, the oil.resistant rubber components undergo pressurization and sealing procedures facilitatedby fasteners. The primary culprit behind oil leakage in oil-immersed transformers isinadequate sealing,...Read more -
Guide to Transformer Electrostatic Shields (E-shields)
What is an E-shield? An electrostatic shield is a thin non-magnetic conductive sheet. The shield can be copper or aluminum. This thin sheet goes between the transformer’s primary and secondary windings. The sheet in each coil connects together with a single conductor tha...Read more -
