Reduce the Risk of Unplanned Outages

Generators are among the most critical assets in power generation and industrial energy supply. Faults developing in stator windings, rotors, bearings, or mechanical components can lead to costly outages and extensive repairs.

NEKA provides advanced solutions for continuous generator monitoring and diagnostics, enabling faults to be identified long before they develop into critical failures.

Early Fault Detection

Many generator faults develop gradually over months or even years. Modern monitoring systems can identify:

• Partial discharge (PD) activity in stator windings

• Insulation degradation

• Thermal issues and hot spots

• Mechanical vibrations

• Air-gap and rotor anomalies

• Bearing defects

• Imbalance and eccentricity

• Loose connections and winding movement

Early detection allows maintenance to be planned efficiently and helps avoid unexpected outages.

Online Generator Monitoring

NEKA offers both permanent and temporary monitoring solutions for rotating electrical machines.

​

Partial Discharge Monitoring (PD Monitoring)

Partial discharge is often the first indication of aging or damage within a generator’s insulation system.

Continuous PD monitoring enables operators to:

• Detect insulation defects at an early stage

• Track fault development over time

• Identify affected windings

• Prioritize maintenance activities based on actual condition

By trending PD activity, asset owners gain valuable insight into insulation health and can make informed maintenance and investment decisions.

​

Data-Driven Condition Assessment

Modern generator monitoring is not only about collecting measurements. It is about converting operational data into actionable insights.

NEKA supports customers with:

• Installation of monitoring systems

• Analysis of measurement data

• Trend analysis and condition assessment

• Condition reports and recommendations

• Technical consulting and expert support

• Verification and evaluation of critical alarms

This provides asset owners with a better understanding of equipment risk, condition, and expected service life.
