Condition Monitoring (CM) / Predictive Testing (PT)

“Proactive service of Renovate Winding”

Introduction:

You definitely might have come across a critical situation, wherein your Motor, Servos, Generator, Transformer or Equipment in Panel Suddenly failed, till date it was running ok and suddenly failed, and your production is held up due to that. Now think if you would have known the upcoming failure well in advance, you would have made an alternative arrangement or could have planned the production accordingly.

What is Predictive Test (PT) or Condition Monitoring (CM).

Predictive Test is the process of monitoring a parameter of condition in machinery, such that a significant change is indicative of a developing failure. The use of conditional monitoring allows maintenance to be scheduled, or other actions to be taken to avoid the consequences of failure, before the failure occurs.

CM is the technique served for Condition-Based Maintenance (CBM) (or named as predictive maintenance). Condition monitoring is the study of methodologies to detect symptoms of possible failure in electrical equipment.

What Service We Provide

We Provide Predictive (in advance) up- coming failures/defects in your all kinds of AC/DC Motors, Servos, Generators & Transformers. A Complete Health checkup to avoid un-expected failures, i.e Maintenance with Intelligence.

You can now detect large failure in its Pre Stage.
You can Rectify the same in less time and with less money.
Healthy Relation between Production, Maintenance & Purchase Team.
Maintenance with Intelligence.
Enhance life of equipment

90% Failure are Due to	10% failure are due to
Winding Inter-turn insulation failure	Un-balance Load
Winding Phase-Phase Failure	Foreign Object fall inside machine
Winding Phase-Earth Failure	Single Phasing
Contamination due to carbon/grease/dust/dirt/rusting	Un-balance Voltage
Rotor Stator Rubbing due to bearing loose on shaft, bearing loose in Housing.	Over Load
Bearing Failure	Shaft Shearing due to jerking
Loose contact in connection ring inside motor	Cable Fault
Loose Connection on Lug or Crimping	Drive Fault
High Harmonics Content	Wrong Phase Sequence

We Analyze by comparing following Values

Sr	Parameter	Faults Indicated
1	Resistance	Loose Connection on Lug /Crimping, Connection Ring
2	Tan Delta	Contamination due to carbon/grease/dust/dirt/rusting
3	Impedance	Rotor Bar Crack & Rotor Faults (in slip-ring & generator)
4	Insulation Resistance	Healthiness of Insulation in Ph-Ph & Ph-E
5	Phase Angle	Inter-turn short
6	Current/Frequency Response (I/f)	Inter-turn short
7	Test Value Static (TVS)	Immense Rotor & Inter-turn fault
8	Vibration Level	Bearing loose on Shaft, Bearing loose in Housing, Improper Alignment, loose/overtight belt.
9	Noise Detection	Faulty/Noisy Bearing, Rotor/Stator Rubbing.
