3.7.2 Energy - Displayed Values

The PEL measures the typical energy readings used. In addition, it enables advanced measurements for specialists or
individuals doing in-depth analysis.
Individual power magnitudes for Power Flow Quadrants (per IEC 62053-23) are available by simply scrolling through each
screen display. The values in each quadrant are often used by engineers addressing power flow issues
Energy measurements, which are time dependent (typically 10 or 15 minute integration or aggregation periods), are
displayed sequentially in screens showing all phases. Table 2 shows the readings per network type.
■ The down arrow ▼ scrolls downward and the up arrow ▲ scrolls upward through the displays.
■ Each display is reached by pressing the down arrow ▼.
Energies are measured from the beginning of the recording session. Partial energies are the energies measured for a
defined period (see §4.4.5).
■
Partial Energy is reached by pressing the

Definitions:
■ P+: Total Active Energy Imported (used by load) in kWh
■
P-: Total Active Energy Exported (to source) in kWh
■
q1: Active Energy Imported (by load) in Inductive Quadrant (Quadrant 1) in kvarh
■ q2: Active Energy Exported (to source) in Capacitive Quadrant (Quadrant 2) in kvarh
■
q3; Active Energy Exported (to source) in Inductive Quadrant (Quadrant 3) in kvarh
■
q4: Active Energy Imported (by load) in Capacitive Quadrant (Quadrant 4) in kvarh
■ S+: Total Apparent Energy Imported (by load) in kVAh
■
S-: Total Apparent Energy Exported (to source) in kVAh
Typically, industrial users will focus on the following values. The other values are used for load analysis and utilities.
■ kWh: Ep+ which is the traditional load Active Energy
■
kvarh: Eq1 which is the traditional load Reactive Energy
■
kVAh: Es+ which is the traditional load Apparent Energy
