EL-CID (Electro Magnetic Core Inspection Detection Test)
A portable test equipment three phase induction motor for inspection of rotating electric machine stator cores.
Also known as Electromagnetic Core Imperfection three phase asynchronous motor, it was designed and used to detect insulation failures between laminations of stator cores in generators. We have been using this equipment to test large Generator and High Voltage motors of all sizes.
Originally developed by the three phase motor in England, the EL CID Evolution is a third generation instrument that is proven, reliable and easy to use. The EL CID Evolution tests the condition of a stator core in less time and with fewer resources than the earlier dual speed motor models. The ELCID instrument can be used to test turbo-generators, hydro-generators, and large motors.
It has the advantage that it does not require a large ms motor source to test the largest machines, it requires only 4% of a machines rated flux using a toroidal winding of a few turns. A 3kva supply at 110volt is sufficient to excite a machine of several hundred MVA.
