The e-PCM is an AI-based online generator condition monitoring system designed to continuously assess the condition of three-phase AC generators and their prime movers, the machinery that drives them. Permanently installed as part of the generator monitoring setup; the e-PCM identifies existing and developing electrical and mechanical faults during operation, providing maintenance teams with ongoing condition information to support the management of power generation equipment within a predictive maintenance programme.
Supporting a proactive approach to generator maintenance, the e-PCM helps teams transform equipment condition information into timely maintenance decisions. Some of the key benefits of the e-PCM are:
Powered by self-learning algorithms, the e-PCM monitors electrical signals to evaluate the performance of your entire drivetrain. The system automatically establishes a baseline of normal operation and adapts as conditions change to keep equipment running reliably. Explore the e-PCM processes below.
Installed at the generator control cabinet, the e-PCM collects three-phase voltage and current measurements through electrical transducers.
During its self-learning phase, the system processes these measurements to create a mathematical model, or digital twin, that accounts for operating conditions such as speed and load.
The e-PCM continuously compares operating behaviour against its reference model. Developing faults in the generator or its prime mover can affect the electrical current waveform, creating differences that the system can identify.
When abnormalities are detected, the system assesses the type and severity of the developing fault. Status indicators and detailed diagnostic information communicate the findings to maintenance teams for investigation and action.
The e-PCM system combines generator condition monitoring with electrical measurements, historical data recording and remote access. The following features support day-to-day monitoring, detailed analysis, and integration with existing systems.
Colour-coded indicators display equipment condition, with status levels including Normal, Watch Line, Watch Load, Examine 1 and Examine 2.
Records trends for reviewing changes in equipment condition over time, with recording capacity dependent on the available database size.
Records Power Spectral Density (PSD) curves for more detailed analysis of the measured electrical signals.
Measures active and reactive power, records energy production and operating hours, and provides daily and monthly energy summaries.
Monitors three-phase voltage and current, frequency, power factor and electrical imbalance. Harmonic analysis includes total harmonic distortion and odd harmonics from the 3rd to the 13th.
Supports access to monitoring data through Artesis Enterprise Software and the Artesis IoT Portal, with user access permissions set by facility or equipment.
Provides an email notification tool for diagnostic alerts, allowing monitoring information to reach designated users.
Supports integration with other monitoring systems through Modbus TCP and OPC DA 2.0, with data availability depending on the interface and system configuration.
Fault diagnostic coverage spans mechanical, electrical, and operational faults affecting generators and their prime movers. This includes problems involving rotating components, windings, electrical connections, and operating conditions. Explore the categories below to understand the range of faults the e-PCM can help identify.
Remarks: Applicable fault coverage will depend on the generator type, connected prime mover, and equipment configuration.
