Air-Gap Flux Probe Installation and Testing
What is Air Gap Flux Probe Testing?
Air gap flux probe testing is an advanced method used to detect shorted turns in generator rotor windings. Shorted turns occur when the insulation between individual windings fails, leading to several operational issues, such as:
Load-Sensitive Vibration: This can lead to mechanical stress and potential damage to the generator over time.
Undetected Local Winding Hot Spots: These hot spots can degrade insulation further and lead to catastrophic failures if not identified early.
Excessive Excitation Currents: This increases the operational cost and reduces the efficiency of the generator.
Efficiency Losses: Overall, the presence of shorted turns decreases the efficiency of the generator, leading to higher operational costs and potential downtime.
The flux probe works by measuring changes in the magnetic flux density within the stator-rotor air gap. These changes are recorded at various load conditions and analyzed to detect the presence and extent of shorted turns. By comparing the flux density at each rotor slot with its opposing pole slot, our system can accurately determine the number of inactive or "shorted" turns.
Why Air Gap Flux Probe Testing is Valuable
In today’s competitive electrical power market, predictive maintenance is essential for minimizing maintenance costs and avoiding unexpected downtime. Regular monitoring of your rotor windings using air gap flux probes allows for:
Proactive Maintenance Decisions: Determine the optimal time for maintenance activities such as rotor rewinds, avoiding unnecessary downtime.
Verification of Rotor Integrity: After a rotor rewind, flux probe testing verifies the quality of the work performed, ensuring that the generator is operating at peak efficiency.
Enhanced Reliability: Regular testing helps identify potential issues before they lead to failure, improving the overall reliability of your power generation assets.
When conducting air gap flux probe testing, varying the load on the generator is crucial for obtaining accurate and comprehensive data on the condition of the rotor windings. The primary reason for this is that different loads on the generator produce varying levels of magnetic flux within the air gap, which in turn can affect the detection of shorted turns.
Importance of Varying Load During Flux Probe Testing
Why Does Varying the Generator Load Matter?
Enhanced Detection Sensitivity: Shorted turns may only manifest under certain load conditions. By varying the load, we can observe how the magnetic flux density changes across different operating scenarios. This variation helps in identifying shorted turns that might not be apparent under a constant load.
Comprehensive Analysis: Varying the load allows for a more complete analysis of the rotor windings. Different loads can induce different stress levels on the insulation, potentially revealing weaknesses that would go unnoticed if the generator were tested under a single, constant load.
Accurate Diagnosis: The relationship between load and magnetic flux is not linear, meaning that the effects of shorted turns can become more pronounced or less detectable depending on the load. Testing under various loads ensures that we capture the full spectrum of the rotor’s behavior, leading to a more accurate diagnosis.
Testing Under Constant Load:
Limitations: Conducting the test under a constant load can limit the ability to detect all shorted turns. Since certain shorted turns may only become evident at specific load conditions, a constant load might miss these issues, resulting in an incomplete assessment of the rotor’s condition.
Risk of Misdiagnosis: Without load variation, the test may not reveal all the potential issues within the rotor windings, leading to a false sense of security or an inaccurate diagnosis of the generator’s health.
Which is Better?
Varying the Load: Varying the load during air gap flux probe testing is the preferred method because it provides a more accurate and comprehensive assessment of the rotor windings. This approach maximizes the detection of shorted turns and ensures that any potential issues are identified across a range of operating conditions. While testing under a constant load can provide some information, varying the load is significantly more effective. It offers a deeper and more reliable understanding of the rotor’s condition, ultimately leading to better maintenance decisions and improved generator reliability.

Generator Rotor Repetitive Surge Oscilloscope (RSO) Test and Analysis
Overview
The Repetitive Surge Oscilloscope (RSO) test is a critical offline diagnostic tool designed to detect shorted turns in generator rotor windings. These shorted turns can lead to several operational issues, such as increased vibration due to rotor thermal bending, unbalanced magnetic flux in the air gap, and higher excitation demands, which can reduce the efficiency and reliability of the generator.
How it Works
RSO testing involves injecting two identical "twin" signals from opposite ends of the generator rotor windings. An oscilloscope captures the signals and any reflections that occur. The test is based on Time Domain Reflectometry, which uses the principle that a signal encountering a change in wave impedance - like that caused by a shorted turn - will result in a reduced through signal and a reflected signal.
The symmetry of the rotor winding ensures that in the absence of faults, the through and reflected signals will be almost identical. However, the presence of a shorted turn creates a discontinuity in the wave impedance, causing variations in the reflected signals. RSO testing detects these variations, allowing for the precise identification of shorted turns.

Electromagnetic Core Imperfection Detection (EL-CID) Testing
Overview
Electromagnetic Core Imperfection Detection (EL-CID) is an advanced diagnostic test used to identify imperfections in the electromagnetic core of a generator. These imperfections, if left unaddressed, can lead to inefficiencies, potential failures, and costly repairs. EL-CID testing is particularly valuable because it allows for the early detection of core issues without requiring the generator to be fully operational, providing a crucial insight into the health of the generator's core.
How it Works
PHASE Signal: This part of the signal is in phase with the reference signal and is primarily due to the magnetic flux resulting from the core excitation. The PHASE signal is relatively large and is present throughout the core, regardless of the presence of faults.
QUADRATURE Signal: This component, detected at a phase angle of 90° from the excitation field, is induced by fault currents in the core. The QUADRATURE signal is critical for identifying imperfections in the core, as it indicates the presence of induced fault currents.
EL-CID testing involves scanning the core surface of the generator longitudinally along the stator winding slots. During the test, an operator uses a Chattock potentiometer placed at the outer edges of two adjacent slots to detect any potential imperfections. The EL-CID system measures two main components of the signal:
The EL-CID system processes these signals using a reference input from the excitation current, separating them into their respective PHASE and QUADRATURE components. The processed signals are then recorded to create a series of traces, which display the sensor position along the bore (x-axis) and the amplitude of any fault currents (y-axis). These traces allow for detailed analysis and identification of core imperfections.
Our EL-CID Test Services
Core Imperfection Detection: We conduct EL-CID testing to detect imperfections in the electromagnetic core of your generator. This sensitive test, which requires the removal of the rotor from the generator, can identify even minor damage that may affect the generator's efficiency and reliability.

Partial Discharge (PD) Monitoring & Device Installation
Overview
Partial Discharge (PD) testing is a critical diagnostic tool used to assess the condition of the insulation in generator stator windings. PD testing can be performed both online (while the generator is operational) and offline (with the generator de-energized). These tests are essential for identifying insulation degradation early, allowing for timely maintenance and preventing costly failures. Systems Approach West offers comprehensive PD testing services, including the installation of PD monitoring devices, analysis, and reporting, to ensure the long-term reliability and efficiency of your power generation equipment.
How it Works
Online PD Testing: Online PD testing is conducted while the generator is operational, offering real-time insights into the insulation condition under normal load conditions. This test focuses on the highest voltage sections of the stator windings, where insulation stress is most likely to occur. Online PD testing is less invasive than offline testing and can be performed without taking the generator offline, making it an excellent tool for monitoring and early detection of insulation issues.
Ongoing Monitoring: Online PD testing provides continuous data on the insulation's condition, allowing operators to detect and respond to emerging issues promptly. This proactive approach helps in preventing unplanned outages and extending the operational life of the generator.
Offline PD Testing: Offline PD testing involves energizing each phase of the generator stator windings individually, while the other two phases are shorted and grounded. This testing method directly energizes the stator windings at both ends, typically resulting in higher Partial Discharge (PD) levels compared to online testing. The test is designed to provide a detailed analysis of the insulation condition across the entire winding, including areas not exposed to high voltage during normal operation. The offline PD test is particularly valuable for trending purposes, helping to monitor insulation health over time.
Phase Plots and Classic PD: During offline testing, phase plots reveal the relationship between the PD pulse and the phase-to-ground reference voltage. This data helps identify the origin of PD within the slot portion of the coil. Classic PD, usually occurring in the slot section, is a key indicator of insulation stress in these areas. The test results are analyzed in 3D snapshots, providing a comprehensive view of PD activities across almost all winding regions. It’s important to note that offline PD test results should be used for trending rather than condemning the insulation, as they are more sensitive and cover areas typically not exposed to high voltage.
