Push  (Graph) to display the measured values in a
chart. The table on the right side of the screen shows the
highest and lowest value of the graph measured with the
average calculation interval. Triangular indicators point to
the measurement value.
Energy
Not available on load studies without a nominal
voltage.
Determine the energy consumed/delivered since the
logging session has been started.
Parameter
Active Energy (Wh)
Apparent Energy (VAh)
Reactive Energy (varh)
The Demand screen shows the values for:
•
Consumed energy (= forward energy) in Wh
•
Maximum Demand in W. Maximum demand is the
highest active power measured over the demand
interval and is often part of the contract with the
electricity supplier.
•
Energy cost. The currency can be configured in
instrument settings. See page 45 for more information.

PQ Health Overview
The PQ Health Overview is available on 1738 or 1736 with
1736/Upgrade or IEEE 519/Report license. This screen
shows a pass/fail analysis based on limits defined by the
power quality standard EN 50160.
The screen includes the parameters for:
•
Frequency
•
Voltage Variations
•
Voltage Harmonics
•
Unbalance
•
Events
The frequency, unbalance, and events have a single bar,
voltage variations, and voltage harmonics shown in three
bars that depend on the configured topology.
The length of a bar increases if the related parameter is
further away from its nominal value. The bar turns from
green to red if a maximum allowed tolerance requirement
is surpassed. When the standard defines two limits for a
parameter (for example, voltage variations have a limit for
95 % of the time and limit for 100 % of the time) the bar
changes from green to orange when the parameter
surpasses the 95 % limit but does not exceed the 100 %
limit. For more information go to
search for the white paper, Measurement Methods.
