Recently time consuming testing procedures in test labs have been replaced by on-site oil testing procedures. There are various manufacturers of portable oil testers including Baur, HV Diagnostics and Megger.With low weight devices in the range of 20 to 40 kg tests up to 100 kV rms can be performed

There are two ways of cooling the transformer:First, the coolant circulating inside the transformer transfers the heat from the windings and the core entirely to the tank walls and then it is dissipated to the surrounding mediumSecond, along with the first technique the heat can also be transferred

Low voltage power is described as power supplied from a transformer of 30 volts or less. The transformer actually steps down and converts 120-volt power to 30 volts or less.Transformers are normally mounted on a junction box. Sometimes transformers have more than one voltage connection point, called

Disclosed is a portable apparatus and method for purifying lubricating oil in remotely separated devices, such as gearboxes and motors on oil well pumping equipment. The apparatus is mounted on a vehicle, such as a trailer, and has separate tanks thereon for holding volumes of oil. A flexible condui

Transformer oil is one of the very important component in oil immersed transformers. The life expectancy and satisfactory operation of transformers are mainly depend on the oil in which is immersed.The transformer oil performs two very important functions.1. It creates an acceptable level of insulat
