The absence of lines indicating the percentage implies that the input current is less than 20% of the CT
Primary value.
Phase Sequence Indication
It indicates the rotation of input phasor vectors :
clockwise/ counter-clockwise.
In case the input is absent or the phase sequence is neither L123 nor L321, the phase sequence indication is not
shown.
2. MEASUREMENT AND ENERGY/COUNTER SCREENS
In normal operation, the user is presented with two simultaneous screens:
1. One of the Measurement screens out of the screens of Table 1.1 / 1.3 / 1.4 .
These screens may be scrolled through one at a time in an incremental order by pressing the respective key. Few
important screens are explained in Section 2.1 to 2.7.
2.One of the Energy/Counter screens out of the screens of Table 1.2.
These screens may be scrolled through one at a time in an incremental order only by pressing the “Enter key” to roll
over again in the same order. Few important screens are explained in Section 2.8 to 2.10
Load Graphics
Load Graphics indicates the input current as the percentage of the CT Primary value. This indication is available for
all measurement screens. For example, consider CT Primary to be set at 5A, then the input current of 2.5 A
indicates 50% as shown below.
