YCTC-9901 Transformer Capacity Tester

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 ACvoltage),6-channel AC sampling and A/D converter, DSP,keyboard,

LCD display, and a Micro-printer etc.

Test functions for capacity of distribution transformers.

Test functions for distribution transformer' s no-loadcurrent, no-load loss, short-circuit voltage, 

load loss, andother 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.
