Answer: Industry convention for color coding in 3 Phase 208V electrical systems assigns the color black to phase A, red to phase B, Blue to phase C, and white to Neutral. Leviton‘s 100A and 200A solid core CTs are coded with the same colors (on the body of the CTs and on the wires) to help...
A: Yes. You should try to avoid extending the native CT leads by locating the meter next to the circuit breaker. If you must extend the leads, take into consideration the following inaccuracy contributors. Here are some of the factors that will affect accuracy when using long CT leads:
1. Wire...
Answer: The meter should not be used in this configuration. The per-phase energy, power, voltage and amperage values in this configuration will be correct, however the Line-to-Line voltage will be calculated for a balanced 3phase system, and will not represent the actual L-L voltage. If the...
Answer: Yes. The meter must be installed with the neutral terminal disconnected. Note: Line-to-Neutral voltages will be reported for a virtual neutral. (e.g. L-L=480V, L-N=277)
Answer: The meter should not be used in this configuration. The per-phase energy, power, voltage and amperage values in this configuration will be correct; however the Line-to-Line voltage will be calculated for a 3phase system, and will not represent the actual L-L voltage.
This document summarizes the application of a Series 4000/4100 Meters on a three phase, four wire delta service for a cost-effective solution for monitoring multi-phase tenant energy usage.
The purpose of this technical note is to identify specific installation requirements associated with the S8000 Meter platform for 3PH Delta service configurations.
