ELECTRICAL TESTING
Current Transformer Tester
Primary Injection Test System • Test several assets (e.g. CT, VT, CB, power
• Automatically performs current trans- former (CT) excitation test, measures CT winding resistance and CT current- ratio (range is 0.8 to 5,000 to 1) • Automatically demagnetizes CT under test
transformer) or different parts of an asset (e.g. core, windings, bushing, insulation) • Perform numerous tests (e.g. ratio, polarity, burden, excitation current) • Voltage and current injection with variable frequency • Suppression of mains-related interference and disturbances
• Test voltage range for CT excitation test (50, 300, 500, 1200 or 2000 VAC) can be selected, then raised or lowered automatically • Measures DC resistance (100µΩ to 10Ω) of CT winding under test • Store up to 140 test records (10 excitation tests per record)

Transformer Turns Ratio Tester
Transformer Turns Ratio Tester
• Measure turns-ratios from 0.8 to 15,000 using IEEE C57.12.90 measurement method • Transformer turns-ratio, excitation current, and phase-angle readings are displayed • Three test voltages: 8 VAC, 40 VAC, and 100 VAC
• Performs specific test for each transfor- mer type (such as single phase, delta to Y, Y to delta, delta to delta, or Y to Y) with-
out having to switch test hookup cables • Three test voltages (8, 40, and 100 VAC) • Automatic transformer phase detection feature can detect 67 different transformer types • Store up to 200 test records with each test record containing up to 99 turns-ratio, excitation current, and winding phase angle
• Capable of detecting 130 different 3-phase transformer types • Store up to 112 test records and download via RS-232C and USB interfaces

Sweep Frequency Response Analyzer
Insulation Analyzer
• Power Factor/Tan-Delta testing to confirm insulation integrity • Capacitance testing to measure physical changes
• Detect mechanical failure or movement of windings due to short circuits, mechanical stresses or transportation • Sends excitation signals to transformer and measures the returning signals • Auto-scales each frequency measurement from 10 Hz to 25 MHz for an overall dynamic range of 80 dB with a ±1 dB accuracy
• HV turns ratio testing to detect shorted turns or winding damage • Leakage reactance/short circuit impedance testing to evaluate winding deformation • Single phase excitation current testing to evaluate transformer magnetizing circuit
