Configuration for 3Phase firmware

The configuration for the 3 Phase firmware inherit mostly from the individual channel firmware documented below.
Over Serial Configuration - Sketch 3.0

This applies for firmware RPICT4V3_3Phase_V5_v1.2.

The 3 Phase firmware allows for computation of three power node at the same time. As opposed to the individual firmware which compute each channel one of after the other.

Only 2 nodes are computed.

• 1 3Phase node using
  • CT1/V1 for L1
  • CT2/V2 for L2
  • CT3/V3 for L3
• 1 Current node
  • CT4 as current only

This is an example configuration.

The parameter we focus on here if CHTYPE. This sets how the channels appear in the output. This is a list of field type to output. The table below give sthe meaning of the numbers.

code	Channel Type	Description
4	Irms	Rms current in Amps
5	Estimated Power	Estimated Power in Watts. This is Irms*Vest.
7	Temperature	Temperature (Celsius). Only for RPIZCT4V3T1 & RPIZ_CT4V3T2.
