Harmonics Plot
Table of Data Points
For both views, a table below the graph provides the numeric values as well. This table
can be saved as a CSV le.
The Power Xpert Meter measures and accumulates three kinds of energy values every
60 cycles: Real Power (Watts), Reactive Power (VAR) and Apparent Power (VA). Real
Power and Reactive Power take direction into account, and so are recorded for forward,
reverse, net and sum.
These measurements are used to calculate accumulators for the kWh Forward/Reverse,
Net and Sum: kVARh, Lag/Lead, Net and Sum, and kVAh.
Real Power (Watts)•
Reactive Power (VAR) is the product of the voltage, the current, and the sine of the •
phase angle between them.
Apparent Power (VA) is the square root of the sum of the squares of the active and •
reactive powers.
