Fli-6
To identify a flicker source 3 or more channels are essential.
That is what FLI-3 or FLI-6 provides. 
ZIRO-F6
Makes snapshots of the transient events of electric power systems,
like switching surges, short circuit currents,
voltage swells or sags, and enables
the evaluation of the stored events
 
VDC-xx
Capacitive, resistive or compensated voltage dividers enable the precise
measurement of asymmetry , harmonics, and other voltage related quantities,
due to their high accuracy and good frequency response.
