Advantage: Many small events that are detected if the mains voltage is close to the
threshold are concatenated to one main event.

Setting up a Logger - Interharmonics (A)

Interharmonics (maximum 5)
Up to 5 interharmonic frequencies can be selected. Voltages and currents with these
frequencies are monitored.
Interval data and statistical data are recorded for each interharmonic.
Classes between 1 % and 11 % of V
each phase and each frequency. The statistical data are used for the
analysis of signaling voltages (ripple control signals) according to EN-
50160.
Measurement Principle
Specify measurement method: 200 ms maximum or minimum value, 3 s maximum value,
or mean value during the interval period. Thus precise monitoring of ripple control signal
levels can be performed.
Frequency Measurement
Absolute: The absolute measurement is based only on the frequency.
Relative: The relative measurement is based on a frequency in relation to the fundamental
of the input signal.
Special Transformer (A, P)
In this field, a maximum of +9 ° phase shift can be corrected by entering –9 °. For an
inductive (lagging) error of 9 ° the measurement results are corrected with –9 °.

Reset

Ensure that the data transfer is not interrupted during this
process. Interruptions could cause problems and the RESET
must be repeated from the beginning.
This screen allows you to reinstall the firmware of a Logger.
This function is a service tool and should not be used during the normal
operation of the Logger. In case of problems (example, no RS232
communication possible to Logger) RESET allows transferring the
firmware to the Logger.
To reset firmware to the Logger:
26
1. Select Logger>Reset. The Reset screen appears.
2. Turn off the power supply of the Logger. Click OK to confirm.
PQ Log prepares the serial port for the firmware download mode.
