describes the application of two relatively new diagnostic techniques for the determination of insulation condition in aged transformers. The techniques are (a) measurements of interfacial polarization spectra by a DC method and (b) measurements of molecular weight and its distribution by gel permeation chromatography. The techniques are (a) measurements of interfacial polarization spectra by a DC method and (b) measurements of molecular weight and its distribution by gel permeation chromatography.

A buck“boost transformer is a autotransformer used to make small adjustments to the voltage applied to alternating current equipment. Buck“boost connections are used in several places such as un interruptible power supply (UPS) units for computers in the tanning bed industry. Operating electrical equipment at other than its designed voltage may result in poor performance, short operating life, or possibly overheating and damage.For large adjustments in voltage (more than 15% to 20%), usually a two-winding transformer is used with t ....etc

Magneto-optical current transformer technology (MOCT)
An accurate electric current transducer is a key component of any power system instrumentation. To measure currents power stations and substations conventionally employ inductive type current transformers with core and windings. For high voltage applications, porcelain insulators and oil-impregnated materials have to be used to produce insulation between the primary bus and the secondary windings. The insulation structure has to be designed car ....etc

How to use a mains transformer (for instance 110-230 Volt and 50-60 Hz) in an electronic project. Do's and dont's with mains transformers in home brew electronics.
Saturation of the core means that the core gets more or less permanenty magnetised. In that case the magnetic field is not built up (and decreased) quickly enough (50 Hz -60 Hz), the permanent field acts as a sort of brake for quick magnetic changes and the power cannot be well transferred from the primary to the secundary coil. The core gets heated up more or less, it gives lo ....etc

Definition
An accurate electric current transducer is a key component of any power system instrumentation. To measure currents power stations and substations conventionally employ inductive type current transformers with core and windings. For high voltage applications, porcelain insulators and oil-impregnated materials have to be used to produce insulation between the primary bus and the secondary windings. The insulation structure has to be designed carefully to avoid electric field stresses, which could eventually cause insulation breakdo ....etc
