Once CTs are installed and configured, Verdigris provides visual indicators to help you validate the configuration of the installed CT is set correctly.
The indicators are categorized into three colors:
POSITIVE (green) if total real energy consumed over the last 24 hours is at least 0.4% of the CT rating and the PF > 0.6
for SmartCT (90A) = > 1KWh
for Hinged CT (200A) = > 2.3KWh
for Coil CT (500A) = > 5.76KWh
NEGATIVE (red) if any 15 minutely period over the last 24 hours is < -0.4% of CT rating
for Smart CT (90A) = < -42W
Hinged CT (200A) = < -96W
Coil CT (500A) = < -240W
INSUFFICIENT (grey) if not Positive and not Negative. The data in this case is often "noise" and cannot be technically validated.
CTs can be easily reconfigured to a different phase and polarity setting. All historical data (starting August 1, 2023) is recalculated and backfilled.
