In case you missed it:

Below is an extract from a Report commissioned by Holcomb and undertaken by Andrew P. Anselmo of Clipboard Engineering in October 2022. http://clipboardengineering.com/about-2/

The official report (27 pages) was amended inhouse by Holcomb as is it did align with Holcomb.
The official report questioned the testing procedures of Holcomb and incorrect wiring to achieve increased power output.

[Extract start]

System B (Figure 10) was examined on Wednesday, October 26, 2022 through Friday, October 28, 2022. This device is a three phase to three phase converter. Power was supplied by in-building inverters, that create three phase power, in a delta configuration.

Tracing of wires and connections for the DENT units turned up a potential issue of power measurement, which may have been the cause of anomalously high output readings. In the standard configuration of inputs as per the DENT manual (Figure 11), power output was less than power input ( Figure 14). In the configuration used by HES (Figure 12), power output exceeds power input (Figure 13). The standard measurement protocol has L1=black, L2=red, and L3=blue (1-2-3):

The explanation put forth by HES is that the construction of the device has the first leg of the input power influencing the second leg, and so forth, which is the reason for the configuration of the DENT current and voltage sensors. The HES protocol has L1=blue, L2=black, and L3=red (3-1-2):
Note that for the DENT voltage/current monitoring systems, the LEDs on the units have the following meanings: ▪ LED is red—there is a CT voltage phase placement error (or the Power Factor is less than 0.55) ▪ LED is blue—the CT is on backwards (-kW) with the arrow pointed away from the load ▪ LED flashes red and blue—CT is on backwards and on the wrong voltage phase.
