Chapter 8 Power Parameters
Figure 1: Explanation of Power Parameter Signs
The following chart illustrates the reported power parameters based on the
chosen voltage mode. Parameters that do not have an "X" will report 0.
IMPORTANT
The E3 Plus model EC5 will report 0 for all power based
parameters if the voltage is below 50V L-L .
IMPORTANT
The E3 Plus model EC5 is capable of reporting power values
when the voltage is greater than 690V L-L and for frequencies
less than 40 Hz or greater than 80 Hz; however, the accuracy of
the value may be compromised.
