The transformer capacity Test Instrument is a digital, portable instrument designed for measurement of distribution transformers\' capacity, loss and other parameters. It integrates the functions of off-line measurement of distribution transformer capacity, no-load current, no-load loss, load loss, impedance voltage and other power frequency parameters.
The instrument is composed of the rechargeable battery (built-in), DC-AC inverter (invert DC into a three-phase, 50Hz AC voltage), 6-channel AC sampling and A/D converter, DSP, keyboard, LCD display, and a Micro-printer etc.
Features & Functions: Test functions for capacity of distribution transformers. Test functions for distribution transformer\' no-load current, no-load loss, short-circuit voltage, load loss, and other parameters. Automatic correction functions:- Test voltage correction (no-load test at non-rated voltage).
- Current correction (load test at non-rated current)
- Waveform distortion correction (voltage waveform distortion under no-load test),
- Frequency correction (correction for test source frequency impedance Voltage and no-load loss).
- Reference temperature correction.
Indicate if any partial defects occur in the transformer\'s magnetic circuit, according to the results of no-load test for one phase. Indicate if the voltage waveform of no-load test power supply is qualified. Histogram, displaying 2-51st harmonic of the six Signals in real time. Oscillograph, displaying the six signals in real time. Wide range of limited measurements. Color TFT, high brightness, wide temperature LCD display Built-in rechargeable high-energy batteries. Built-in mini-printer.
