EnerLyzer
Real-time measurement and signal recording for CMC test sets.
Measure, Record and Analyze
EnerLyzer transforms the CMC test set into a multifunctional measuring, recording and analysis device. Each of its binary inputs can be configured as an analog measuring input and can then directly measure voltages as high as 600 VRMS. Currents are acquired via the measuring shunts 1 or current clamps. The CMC test set can be used for conventional testing and simultaneously for measuring with EnerLyzer. EnerLyzer is available in two versions: EnerLyzer and EnerLyzer Classic.
EnerLyzer: The modernized version with an extended range of functions, available for CMC 430 and CMC 500.
EnerLyzer Classic: The former version, available for CMC 356 and CMC 256plus.
Broad Range of Applications
EnerLyzer offers a wide range of views and analysis tools: you can display both direct and derived measurands in multimeter view, as a phasor diagram, a time signal, and other views. You can also use your CMC as a multichannel transient recorder. In addition to the analysis capabilities of EnerLyzer, the TransView license is included to enable an even more detailed view into recordings.
Combined, these tools are perfectly suited for all kinds of troubleshooting tasks during secondary testing and allow you to immediately evaluate the corresponding system parameters as well as to perform transient measurements and recordings.
Various application notes are available in the Customer Portal.
Troubleshooting during commissioning or secondary testing
EnerLyzer can levy measurements from voltages, currents, and binary signals. In combination with the various visualization options ranging from multimeter, phasor, and time signal view over binary trace till bar graph (harmonic spectrum), EnerLyzer is the perfect troubleshooting tool during secondary testing.
Additionally, the general measurement functions of EnerLyzer also make it ideal for plausibility or wiring checks.
Transient recording and analysis of switching operation, transformer inrush, and motor startup
EnerLyzer enables you to measure transient events like:
- Switching of circuit breakers
- Transformer inrush
- Motor startup.
Recording, understanding and thoroughly analyzing these types of events helps
- to avoid damage to equipment (e.g., voltage surges in consequence of switching operations),
- with the exact parameterization of protection relays (e.g., modelling of motor startup characteristics),
- to check the proper function of auxiliary systems (e.g., point-on-wave controllers for circuit breakers),
- to verify the correct function of protection systems (e.g., harmonic blocking function for transformer inrush).
Measurement and analysis of synchronizing events
You can use EnerLyzer for measurements during generator synchronization with synchro-check and other synchronizing events.
Against the background of having multiple voltage outputs, the CMC is the perfect test set for injecting and measuring back at the same time when testing paralleling devices.
Circuit breaker checks
EnerLyzer allows you to perform simple circuit breaker checks. The software facilitates the indirect timing measurement of the main contacts of a circuit breaker with a CMC. The method is ideal for systems where the main contacts are not accessible, such as switchgear in operation or GIS, or if there are no auxiliary contacts available.
Additionally, you can utilize EnerLyzer for a first trip measurement and the recording of coil and motor current.
Measurements in IEC 61850 hybrid or digital environments
Real-time communication with GOOSE and Sampled Values brings new challenges for measurement and troubleshooting, especially when conventional signals and digital signals are combined (hybrid substations). Here you find more information and a comparison of our tools for measurement and analysis in power automation systems.
EnerLyzer supports the common use case where conventional voltage and current signals need to be recorded along with GOOSE signals. With the help of the GOOSE Configuration Module, EnerLyzer can configure these GOOSE messages, which can also be used as triggers for the measurement. In addition, the new EnerLyzer version available on the CMC 430 and CMC 500 supports the recording of Sampled Values signals according to IEC 61850-9-2 LE.
Functionalities for power quality analysis
EnerLyzer comes with various PQ measurement functionalities. These allow you to check the quality of the supplied energy, investigate possible system perturbations or detect sources of disturbances. It features the measurement of:
- Voltage and current unbalance
- Frequency
- Voltage dips, swells, and interruptions
- Display of harmonics of voltage and THD
Powerful multimeter
A basic, yet very powerful application for EnerLyzer is its use as a multimeter to measure the following quantities:
- Analog voltages and currents
- Binary signals
- Total harmonic distortion (THD) and harmonics
- Powers*
These multimeter functions are available for CMC 430 and CMC 500 without an additional license.
