This chapter details all types of registers created by the DR60.
The waveform recorder registers the actual voltage or current signal being applied to
the analog channels. It captures the instantaneous values of the signal at a configurable
sampling rate of 256 or 512 samples/cycle.
The condition that initiated the waveform recording is called trigger. A trigger happens
whenever there's a violation of digital (binary or GOOSE inputs) or analog thresholds.
Other ways to create waveform records are by cross-trigger signal coming from another
recorder or by a manual trigger.
The following values are recorded by the waveform recorder:
•
Voltage waveform of all voltage circuits (A, B, C, and N);
•
Current waveform of all current circuits (A, B, C, and N);
•
Transducer waveform of all transducer channels;
•
Binary Inputs
•
Binary Outputs
•
GOOSE Inputs
The following durations are configurable in the waveform recorder:
