Sweep Frequency Analysis of Transformers

Sweep Frequency Analysis of Transformers

Sweep Frequency Response Analysis is the injection a range of frequencies into a winding of a power transformer. If the transformer is built correctly with no imperfections or faults, the frequency response plot of that particular type of transformer becomes the...
Transformer Efficiency Testing

Transformer Efficiency Testing

Transformer Efficiency Testing The efficiency of an ‘ideal’ transformer would be100% but in reality of course, this doesn’t exist because all transformers have losses. Transformer losses comprise copper loss, coreloss and stray losses. As power levels of power...

Power Quality Analysis for Electricity Utilities

Power Quality Analysis for Electricity Utilities The needs of Australian & New Zealand power utilities differ significantly from those overseas where most analysers are designed. Our distribution network is predominantly overhead through extremes of environments...

Cable Identification

CABLE IDENTIFICATION If you are intending to cut a cable, particularly a high voltage cable, it is imperative to be 100% sure it is right cable and the de-energised cable otherwise the result may be catastrophic! Cable Identification or Location? Cable Identification...
