For drytype reactors, having a rated voltage of Um less or equal to 35 kV, the standard allows an alternative turn-to-turn overvoltage test, which is described in Appendix E of the document. Recording these waveforms to date is done with oscilloscopes, triggered manually, or by the generator, to record the first and the last oscillogram. With further research, finding the exact iec 60076-6 and reason of damage for faulty 600076-6 may be possible without conducting additional tests.
Using the software introduced in this paper, the behaviour of faulty reactors can be observed live during the turn-to-turn overvoltage test.
These recorded data is then compared and the test result is determined. In case of iec 60076-6 faulty reactor, it is possible to see how the reactor’s response to the impulse changes over time.
For any questions in connection with the on-line library, contact: Data of the measurement are analysed in real-time and shown graphically and in text on screen for the test operator to monitor.
By iec 60076-6 a PC-oscilloscope, the measurement data can be acquired uec a personal computer for further analysis, allowing detailed real-time insight into the reactor under test.

Power transformers – Part 6: Reactors
Automation of the measurement and evaluation of turn-to-turn overvoltage tests on dry-type iiec voltage reactors according to IEC Appendix E. The basic procedure of the test is to apply a minimum of voltage pulses with either 1,33 or 1 times the peak value of the rated voltage for 6076-6 and indoor reactors, respectively, which need to be applied within one minute.
The algorithm 6007-6 used as iec 60076-6 basis for a demonstration software. Costs of electric service, allocation methods, and residential rate trends. In the scope of this paper, using this data, an algorithm to ascertain detailed parameters of the reactor, like inductance and resistance, are developed and presented. Substation earthing system design optimisation through the application of quantified risk analysis.
Part of these tests is a routine test using lightning impulse voltages. In order to pass the test, the frequency of the waveshape of the reactor’s response to the first impulse or an reference impulse with lower voltage must not differ from the response to the last of the impulses.
Running on a modern computer, the software is iec 60076-6 to capture 6006-6 evaluate data of the running test in real-time iec 60076-6 show, if the behaviour of the reactor changes during the test. Today all non-high-frequency reactors rated 1 kvar single phase or 5 kvar three phase and above are tested according to IEC
