APPLICATION

This is a common test panel for distribution/ power transformers of different specifications. The user can perform most of the factory tests, as per the relevant IS standard for the transformers. The panel consists of power analyser, meters for high voltage test, meters for induced voltage test etc, control for all the tests, protection and interlock circuits so that a single panel can be used to conduct a number of tests using only one dimmerstat and the associated devices

 
FEATURES
• A single measurement and control center.
• Simple & Easy to use.
• All digital & accurate meters.
• Electrically interlocked for safe operation.
• Wide range of transformers can be tested.
