TESLA 4000 Multi-timeframe Power System Recorder

TESLA 4000 is an easy-to-use and cost effective, state-of-the-art, multi-time frame (simultaneous) digital fault recorder. Its integrated Phasor Measurement Unit (PMU) functionality streams synchrophasor data for wide area monitoring. Enabled with IEC 61850 protocol, TESLA has advanced communication capabilities that, together with its powerful recording features, provide the most versatile and complete monitoring of power system health.

With over 1000 user definable triggers, TESLA creates records simultaneously in 3 time domains (fault (fast), swing (slow) and trend records), and also creates event logs. The CDR creates continuous records without triggers which, together with the fault, swing and trend records, provide wide area visibility of system performance. The CDR also creates redundancy in PMU data.

TESLA DFR has 256 virtual inputs to record digital status changes contained in IEC 61850 GOOSE messages, expanding its monitoring capabilities.
