Types

Description

LMA Types

The LMA API relies on a set of unique data structure, enum's and other defined types to operate, here these are outlined.
Checkout the Storage topic to see what types are particularly useful for non-volatile storage.

Enumeration Type Documentation

LMA_Status

enum LMA_Status

Phase status.

Enumerated type to indicate events detected per phase

Enumerator
LMA_OK	No Problems.
LMA_NO_ACTIVE_LOAD	No Active Power (P < LMA_Config.no_load_p)
LMA_NO_REACTIVE_LOAD	No Reactive Power (Q < LMA_Config.no_load_p)
LMA_NO_APPARENT_LOAD	No Apparent Power (S < LMA_Config.no_load_p)
LMA_VOLTAGE_SAG	Vrms Sagged (Vrms < LMA_Config.v_sag)
LMA_VOLTAGE_SWELL	Vrms Swelled (Vrms > LMA_Config.v_swell)
