4 Recommended Recording Practice and
Instrument Connection
In following section recommended measurement and recording practice in described.
4.1 Measurement
campaign
Power quality measurements are specific type of measurements, which can last many
days, and mostly they are
performed
only once. Usually recording campaign is
performed to:
•
Statistically analyze some point in the network.
•
Troubleshoot malfunctioning device or machine
Since mostly measurements are
performed
only once, it is very important to properly set
measuring equipment. Measuring with wrong setting can lead to false or useless
measurement results. Therefore instrument and user should be fully prepared before
measurement begins.
In this section recommended recorder procedure is shown. We recommend to strictly
follow guidelines in order to avoid common problems and measurement mistakes.
Figure bellow shortly summarizes recommended measurement practice. Each step is
then described in details.
Note:
PowerView has
ability to correct (after measurement is done):
•
wrong real-time settings,
•
wrong current and voltage scaling factor.
False instrument connection (messed wiring, opposite clamp direction), can’t be fixed
afterwards.
