Types of Events and Triggering Functions
Events are logged by triggers, and in the 1133A are separated into four groups: DSP Triggers, Power
Quality Triggers, System Level Triggers and external. DSP Triggers include any measurement
processed by the DSP that meets a logical condition, such as the frequency changing by 0.1 Hz, or
the line voltage dropping below 110 volts. Power Quality triggers conform specifically to methods
