Product Overview
The EL CID™ Evolution Low-Flux Core Tester is the only industry recognized instrument for low-flux core testing identifying inter-laminar insulation breakdown within a stator core.
Stator cores are made of thin laminations of magnetic steel separated by insulation to prevent axial currents. If lamination shorts occur, the high temperatures that result can burn stator coil insulation and even lead to melting of stator cores.
EL CID™ Low Power Core Tester is the only industry recognized and world-wide accepted instrument for reliable and safe detection of stator core inter-laminar insulation faults. EL CID™ Low-Flux Core Tester can also be used for off-line detection of broken rotor bars in squirrel cage rotors.
The only alternative to the Iris Power EL CID™ Evolution Low-Flux Core Test is the Ring Flux (full flux) test which requires large power supplies, considerable manpower, and expensive infrared viewing cameras.

Product Details
Features
- Only one technician is needed to perform the low-flux core test using the EL CID™ Evolution tester
- Safe for core and operator, unlike Ring Flux test which is potentially damaging to the unventilated core
- Iris Power EL CID™ Evolution Low-Flux Core Tester instrument uses an excitation kit to operate the test at only 4% of normal operating flux.
- Measurement results are digitally stored in the PC for analysis and automatic report generation.
- Any imperfections in the core inter-laminar insulation produce fault currents which are detected by a Chattock coil and analyzed by the Iris Power ELAN software.
- Future results can be compared to past results for trend analysis.
The EL CID™ Evolution Low-Flux Core Tester includes the following components:
- EL CID™ Evolution Low-Flux Core Test Instrument
- Chattock Sensors (10, 20, 25 and 30 cm)
- Reference Sensor
- Magnetic Manual Trolley
- Step Iron Trolley
- Calibration Unit
- Switched Turbo Excitation System including 30 m of excitation cables
- Volt Meter and Clamp-on Ammeter
- ELAN CD with Software Licence
- Handbook
- Two Wheeled Transit Cases
Options
- ATEX / IECex certified fiber optic accelerometers (EVAII sensor kits)
- ATEX / IECex certified electro optical drivers
- 4-20mA remote Input-Output units are available
