The DRL6600U is a disturbance recording and fault locating device designed for substations, industrial use, railways, and power generation. It records electrical variables during events like power oscillations, frequency collapses, and voltage fluctuations to support incident analysis and operation maintenance.
The device consists of a recording unit with CPU and hard disk, and a separate HMI. It offers various recording modes, including:
It also provides fault locating capabilities and a cross-platform waveform analysis tool for data analysis on Windows and Linux systems. The device supports manual and remote recording, monitoring, and has basic IED functions like self-supervision and time synchronization.
