Transformer Power Analysis & Testing
The testing of power transformers makes a couple of different measurements necessary, which are described in the international IEC 60076 standard.
Dewesoft data acquisition systems provide key features for complete power transformer testing:
Scope and Vector Scope offer the capability to analyze the voltage ratio and phase displacement of different primary and secondary configurations (star, delta, interconnected star).
Transient recording functionality allows storing all signals at the full sampling rate for detailed analysis. In combination with the trigger functionality failures and transient events (also during long-term measurements of the transformer) can easily be detected.
Analysis according to IEC 60076 standard
Correction of power losses depending on temperature
Additional software sensor calibration
Measure harmonics and symmetrical components

Power Quality Measurement on Transformers
The Power quality module allows measuring harmonics of the voltage and the current up to some hundred kHz. The data can be represented in the percentage of the fundamental frequency as required for the no-load current according to IEC 60076 standard.
The power quality module also automatically calculates the zero-sequence impedance which is required in the power transformer testing
The math library allows us to automatically calculate parameters like the magnetizing current, the iron losses, the main inductance for example out of the no-load test or the stray inductance out of the short-circuit tests.
