1 Gigabyte Extensive Onboard Mass Memory Securely Records All Data
Multiple Programmable Memory Logs Virtually Unlimited Historical Trending Logs
The Nexus® 1500 meter includes vast amounts of memory. A user partitions this memory for log storage by setting up both the number of logs and the number of parameters per log. 8 independent historical logs with up to 64 parameters per log are available. With such extensive memory, the meter will log for years.
Out of Limit Log
Out Of Limit Log
The unit offers an independent out of limit log. This allows a user to download out of limit information to obtain a sequence of events for any occurrence. Utilizing the 1msec clock resolution, the logs can be combined with different metered points throughout a distribution system to provide an accurate system-wide depiction of a power disturbance.
Event-Triggered Waveform Recording Log
The Nexus® 1500 meter records waveforms with a resolution of up to 1024 samples per cycle. The amount of waveform recording is based on the amount of memory installed.
The unit records the waveform when a value goes out of limit and when the value returns to normal. All information is time-stamped to the nearest 1msec. 8 on-board High-Speed Inputs can be tied to the waveform recording.
- Compare Relay Trip and Breaker Timing graphically
- Provides Fault and Breaker integrity analysis
The unit can be programmed to take more than one recording every time an event occurs. Thousands of cycles can be recorded per event.
ITIC/CBEMA Log
The Nexus® 1500 meter stores a separate CBEMA log that records magnitude and duration of voltage and current surges and sags for every power quality event. This allows the user to conduct real time CBEMA analysis without downloading all stored waveforms. The separate CBEMA log also allows the unit to provide a more comprehensive picture of power quality over time.
