Laser alignment is an advanced solution that uses optical technology to perform precise shaft alignment.
The process of reducing the unbalanced forces that causes vibration and bearing noise.
Use of a superior high tensile strength banding tapes to secure the winding and to resist the centrifugal force when the rotor is rotating.
Coil Winding Machine
Automatic wire guidance in a manner that assures perfectly layered winding, with automatic wire tensioning, which enable us to save time.
Machine Shop and Metalizing
We are performing several kinds of mechanical repair such as re-sleeving of housing, metalizing through electroplating, re-shafting, re-facing of commutators and slip rings, fabrication of motor parts, etc.
We are assessing large hydro generators using GETS – generator electrical testing standards.
A partial or a complete dismantling and re-insulation of core laminations.
A partial or a complete replacement of wedge in stator assembly, either magnetic or non magnetic.
The process by which an abrasive media is accelerated through a blasting nozzle by means of compressed air.
We are conducting a thorough electrical testing for evaluating motors and no load testing up to 4160V.
We are reconditioning and rewinding different types of transformers from smallest control transformers to large power and distribution transformers and also rectifier transformers.
We are assessing large turbo generators using GETS – generator electrical testing standards.
Corona Probe Slot Discharge Test
Offline method of testing stator winding insulation to evaluate partial discharge and corona activity.
Dry Ice Blasting
With the dry ice blasting, dry ice (CO2) particles are propelled to supersonic speed impacting and cleaning a surface. The particles are accelerated by compressed air, just as with other blasting methods.
“GETS – Generator Electrical Testing Standards”
---in the services with specific testing or new testing that we have, to be done in GETS, such as:
Electromagnetic Core Imperfection Detector (ELCID) Test
EL CID testing is a means by which the integrity of stator core intra – laminar insulation can be measured, utilizing minimal electrical input to excite the iron.
Wedge Tightness Detector (WTD) Test
Computerized wedge tightness testing is a method of precisely measuring the stator slot wedge system for its degree of tightness within the core iron wedge grooves.
End Arm Frequency Response Resonance Test / Bump Test
Bump testing is used to assess resonant frequencies and looseness of end windings and connections. It analyzes the natural response of stator end windings upon excitation from a mechanical impulse.
Recurrent Surge Oscillation (RSO) Test
A low voltage (a few volts), high frequency (kHz range) surge wave is injected at each one of the collector rings. The two signals are then compared to determine if the same waveform is observed at each collector ring.
Boroscope is an optical tool suitable for visual inspection of inaccessible areas of the machine such as under the retaining rings of a turbo generator.
Ultrasonic Test (UT)
Ultrasonic Testing (UT) uses high frequency sound energy to conduct examinations and make measurements. Ultrasonic inspection can be used for flaw detection/evaluation, dimensional measurements, material characterization, and more.
