Programming your meter to write any data recorder at continuous intervals lower than 60 seconds
(heavy logging configuration) may cause loss of data in the event of a power failure. Use of an
uninterruptible power supply (UPS) is recommended for such heavy logging configurations if data
needs to be available after a power cycle.
Modifications to these parameters will reset your recorded data. Ensure that you
record all necessary information before writing your configuration changes to the
meter.
PT/CT Correction Screen
The PT/CT Correction screen in the Revenue folder allows you to configure any
transformer correction for voltage and current inputs. Select the parameter and
click Edit to configure either your voltage or current input correction details.
Transformer Loss Screen
Some PowerLogic ION revenue meters support loss compensation in their default
framework. For more information about Loss Compensation, see the Transformer/
Line Loss Calculations technical note or contact Technical Support.
Transformer loss occurs when power is dissipated by the core's magnetizing
inductance (iron loss) and/or impedance of the wiring (copper loss). ION Setup can
calculate these losses for any operating condition if certain parameters of the
power transformer are known.
