PAC-E150
(Multi-functional Integrated Digital Current and Voltage Relay)
Waveform Recording
Waveform Recording can record up to 20 blocks. The resolution is 16 amples per cycle, and
the maximum recording time per block is 0.24 sec (based on 50Hz, 10 blocks). The waveform
records include the sample data for current, voltage, contact input/output status, and
protection elements operation status.
The trigger condition for waveform recording can be composed through EasyLogic of the
internal status of PAC-E150 such as the contact input/output status change and protection
element operation. The trigger position of waveform recording can be set between 0 and 99%
of the total block size.

Figure 3-17 Waveform Analysis of E3RSetTM
Waveform records can be uploaded locally or remotely through E3RSetTM, and data are
maintained even if PAC-E150 loses power supply. As the waveform records are recorded in
the COMTRADE file format, they can be used for fault analysis reproduction through a
protective relay tester.
