Performing a range of standard electrical tests on a regular basis has proven to be an effective way of gaining reliable insight into the operating condition of transformers. But, this has been a time- and cost-intensive job in the past. A true three phase test system can really make a difference.
Rishabh is having the complete basket of low tension current transformers manufactured in a world class CT manufacturing setup consisting of an automatic testing facility for all CTs with a printed Test Certificate...- Santosh R. Bhangale
TRAX is not just another multi-functional test instrument, but rather many intelligent instruments built into one box. The software includes a number of apps, making it fast and easy to perform a large range of different tests. The hardware offers unmatched flexibility and the range of cables and accessories adding even more flexibility, making the TRAX an efficient and time saving system for any user in the world...
There is only one instrument to unpack, power up and configure; the same cable set is used for a whole range of measurements, so the connections only need to be made once; and, when carrying out a range of tests, users of multifunction instruments move quickly and easily from app to app, rather than having to go from instrument to instrument... - Peter Fagerström
To aid in the organization of a corporate or personal library, Megger is introducing a comprehensive series of Transformer Life Management bulletins that broadly cover the fundamentals of managing the life of a transformer...
For certain kinds of measurements, even today, we need to know the correct polarity of the primary and secondary windings in current transformers... - K Sivakumar
This article illustrates the thermal behaviour of transformer with respect to the temperature rise test – and also discusses various factors that influence the test results. The article is also focusing on the causes for transformer failure and with certain remedies to overcome them... - S. Arjuna Rao, G. Girija, Manikandan N, Swaraj Kumar Das
The versatility and performance of Current Transformers (CTs) mean that many of the instruments used for testing and diagnostics of electrical insulation and earthing can be made smaller, lighter, safer, more reliable and less expensive... - Dr Stan Zurek
Though recent tan-delta test sets in the market, which are widely used to assess insulation in high-voltage electrical apparatus, combine versatility with convenience, there is room for further improvement. - Vince Oppedisano
To prove that the transformer meets customer’s specifications and design expectations, the transformer has to go through different testing procedures in manufacturer premises... - D A Suthar
