The Bitronics 70 Series Disturbance Recorders provide a scalable, low-cost distributed disturbance recording solution that meets all three PRC-002 requirements in a single unit that can be installed without an outage. They support IEC 61850 GOOSE cross-triggering without hard-wired contacts and provide independent, high-fidelity waveform capture with two disturbance recording modes and trend recording. They also provide features such as fault location and SCADA communications that can automate a substation where electro-mechanical relays are used.
