7. Seal the revenue lock switch cover if required.
PT/CT correction
PT/CT correction, also called instrument transformer correction, can help reduce the
need to replace transformers in installations where high accuracy is required.
The primary application for PT/CT (potential transformer / current transformer)
correction is to apply correction factors for ratio errors and phase angle errors to
instrument transformers. PT/CT correction is done for each current and voltage input to
the meter and only affects 1-second power meter data and values derived from it, such
as energy or demand. No high-speed, harmonics or waveform values are affected by
the correction.
NOTE:
For those familiar with ION architecture, the relevant 1-second Power Meter
module outputs are compensated using the Instr Xformer (ITC) Correction module,
and therefore so are all other modules that use that Power Meter module’s data.
See the ION Setup online help, available from www.usa.siemens.com/pds, for
instructions on how to configure PT/CT correction on your device.
See the ION Reference, available from www.usa.siemens.com/pds, for detailed
information about the Instr Xformer Correction (ITC) module and how it applies PT/ CT
correction to your device.
