The iTIG Surge and PD Tester for Industrial Applications

Why Do Industrial Users Need an iTIG Surge and PD Tester?

Get the warning you need to prevent unplanned downtime and control operating costs with the iTIG static motor tester and winding analyzer by Electrom Instruments. Over-voltage tests, such as surge and PD, find weaknesses sooner than tests below operating voltage.

The ITIG uses a high-frequency, up to 50 Hz, surge test, which finds more cases of insulation weakness. The surge test is the only test that can find turn-to-turn insulation weaknesses. If undetected, these weaknesses can cause shorts and lead to complete motor failure.

PD measurements provide the earliest indicator of insulation breakdown. The iTIG uses advanced algorithms and digital signal processing to automate the PD test making it quick and easy with no accessories required. PD is used as a predictive maintenance tool by trending measurements over time. For example, if RPDIV trends downward in medium and high voltage motors, that’s a red flag.

The iTIG Comes with Test Reporting and Data Analytics

Test Reporting and Data Analytics with the iTIG

The ITIG features time-saving reporting and robust data analytics tools. Provide the professional reports and analytics your customers deserve.

For large organizations with multiple operators, using multiple iTIGs can save time and avoid hassle by automatically uploading test results to a shared network location.

After testing is complete, use TRPro on your PC to view test results and filter test data. Millions of tests can be saved. Print single reports or multiple reports by selecting the desired tests and select print. To append multiple tests in one report, use the Multi-Test Report option. The PDF report can be customized to include a cover page, equipment information, and any test result or chart selected on the reports configuration screen.

High accuracy Insulation Resistance (IR) testing with the iTIG

High Accuracy Insulation Resistance (IR) Testing with the iTIG

The iTIG features highly accurate Insulation Resistance (IR) testing.  This is made possible by the highly accurate leakage current measurement.  Leakage current accuracy is 2% with a 10pA resolution. This means you see 5 digits after the decimal and the tester will calculate Megohms with currents down to .0005 µA.

When the current is low, small changes in leakage currents mean big differences in IR values such as Megohms, Polarization Index (PI), and Dielectric Absorption Ratio (DAR).

See how the test instrument calculates Polarization Index (PI) and how testers with less accurate leakage current measurements produce inaccurate PI values. Trust the iTIG for accurate PI values, especially when testing motors with low leakage currents.

For more details on the example comparison in the video, see High Accuracy Insulation Resistance (IR) Measurement.

Testing high voltage motors using the Electrom iTIG with the Power Pack on location at Power Zone in Center, Colorado

Field Testing High Voltage Motors with the iTIG and Power Pack

Just because your motor is big doesn’t mean your tester should be. Electrom offers the only truly portable high voltage electric motor testing solutions with output up to 40kV. The iTIG with the Power Pack can be used in the field for surge testing and partial discharge testing with advanced reporting capabilities.

The iTIG is Drop and Vibration Tested

The iTIG is Designed to Be the Most Reliable and Rugged Instrument Available

Drop and vibration testing is conducted on sample prototypes as part of Electrom’s ongoing research and development process. For motor and generator testing in the field or demanding workshop environments, professionals can rely on Electrom’s iTIG.

Getting Started: How to Remove the Lid and Prop the Instrument

Getting Started: How to Remove the Lid and Prop the Instrument

How do you prop up the iTIG to be used for testing? This video demonstrates how to remove the lid and use it to support the instrument. Place hinges even with the edge of the table for best results. Open the lid and remove the test leads. Do the tap: a gentle tap to the left with the right hand will separate the lid from the instrument. Use it to prop the instrument or store in a safe place. Happy testing!

Removing the Instrument from the Shipping Box

How to Remove the Instrument from the Shipping Box

This video demonstrates this simple procedure:

  1. Use scissors to cut the plastic strap.
  2. Using box cutters, cut the shipping tape.
  3. Open the top of the box and pull out the foam inserts. Do Save the foam inserts.
  4. Use you feet to brace the box and pull the instrument straight up using the handle of the carry case.
  5. Place the foam inserts back into the box to use later.
