The iTIG is a complete "all in one" Winding Analyzer. Its main functionis that of an insulation tester designed to safely detect weak orunstable insulation at voltages far below what the apparatus beingtested is designed to withstand.
iTIG Advantages:
MORE SENSITIVE AND ACCURATE FAULT DETECTION: Mostsurge testers have one surge generator or channel. This means onewinding is tested and compared to a stored winding test. The ElectromiTIG uses two independent surge generators operating simultaneously tocompare two windings or coils. This produces a live comparison with ahigher voltage gradient between the two phases under test, thussimulating what motors are subject to during operation. Comparing twolive waveforms makes it easier to see faults that might go undetectedusing only one live channel.
FINDS FAULTS AT LOWER TEST VOLTAGES: Ionization ofthe air surrounding the windings is necessary for detection ofinsulation weaknesses in a surge test. The iTIG generates linefrequency Surge Pulse Rates (50 or 60Hz). This produces and maintainssufficient ionization around fault locations at lower test voltagesthan instruments with lower pulse rates, such as commonly used 5Hzunits.
PREVENTS DETECTED FAULTS FROM WORSENING: Voltage isthe equivalent of pressure causing currents of electrons to flow.Voltage (pressure) is necessary to detect weaknesses (current leaks) inthe insulation of rotating equipment. Leakage current (the flow ofelectrons crossing a fault) should be kept as small as possible toprevent further deterioration of the insulation. The current is afunction of the discharge capacitance of the instrument. The higher thecapacitance the higher the current. The iTIG's discharge capacitance isvery low at 0.02uF (20nF) per channel.
EASY TO USE AND READ:
o Computer-controlled oscilloscope functions with color LCD display.
o Large displays of test and output voltage, resistance (Megohms) and leakage current
o Easier to use than previous instruments with multiple report printing options.
PORTABLE ALL IN ONE INSTRUMENT: All tests,including the AC Rotor Bar test, are done with one instrument, noextras. Optional accessories fit in the cover of the ruggedmoisture-proof case which is designed for harsh environments.
BUILT IN SAFETY FEATURES: Improper power lineground and polarity prevents the iTIG from powering up. Limits onleakage current prevent insulation damage and shuts the test down.
All models can perform all of the following tests:
Hipot Tests
Surge Tests
Rotor Bar Tests (Open or cracked AC Rotors)
Step Voltage Tests
Dielectric Absorption Tests
Polarization Index Tests
Armature Tests (DC Rotors)
Form Coil Tests
