HIGH VOLTAGE MACHINES

Sparks Instruments offer online and offline monitoring solutions that provide analysis and diagnostic information regarding the health of your high voltage machinery. This allows users to reliably predict and prevent machine faults, and schedule maintenance and down time accordingly. 

1. PARTIAL DISCHARGE

Partial discharges  are electric current pulses caused by stresses that weaken the winding insulation. They are not the source of winding insulation degradation, but they are a detectable result. 

2. MAGNETIC FLUX

Rotor magnetic flux fluctuations are the result of degradation of the winding insulation caused by installation defects, contamination, load balancing and thermal aging.

3. SHAFT VOLTAGE / SHAFT CURRENT

High levels of voltage on the generator shaft and/or high levels of current on the generator shaft  is an indication of poor grounding shaft performance. 

4. VIBRATION

Insulating material can reduce or expand over time resulting in increased end-winding movement that can cause serious ancillary damage.
