3.4.3 Sensors and Ratios
Press to select the voltage ratios and current sensor’s ratios and range
3.4.3.1 Voltage Ratio
Voltage ratios are used when the voltages are too high for the instrument and
voltage transformers are used to lower them. The ratio lets you display the true
voltage and use it in the calculations.
To choose the voltage ratios, select for phase-to-neutral voltages
(neutral included) or
4V 1/1 or 3U 1/1: every channel has the same ratio.
4V or 3U: every channel has the same ratio to be programmed.
3V+VN: every channel has the same ratio; the neutral has a dierent ratio.
V1+V2+V3+VN or U1+U2+U3: every channel has a dierent ratio.
For ratios, the primary voltages are in kV, and the secondary voltages are in V.
To avoid calculations, you can use a multiplier 1/√3 for both the primary voltages
and secondary voltages.
3.4.3.2 Current Sensors
Select to choose the ratios and ranges of the current sensors
The instrument will automatically display the detected current sensor models.
The dierent current sensors are:
for phase-to-phase voltages (neutral excluded)
MN93 clamp (200 A)
MN193 clamp (100 A)
MN193 clamp (5 A)
SR193 clamp (1000 A)

Current ratios are used when the currents are too high for the instrument and
current transformers are used to lower them. The ratio allows you display the
true current and use it in the calculations.
4A: every channel has the same ratio.
4A+AN: every channel has the same ratio; the neutral has a dierent ratio.
A1+A2+A3+AN: every channel has a dierent ratio.
For the ratio, the primary current cannot be less than the secondary current.
When 2 current sensors of the same type and same ratio are connected in
a three-phase, three-wire setup, the instrument will simulate the third sensor
and give it the same specications as the other sensors. The connection
conguration must indicate which sensors will be present. Then, the instrument
will show the third sensor as simulated.
This menu will only appear for the sensors referenced in the table above.

6. HARMONICS
The voltages and currents can be analyzed as sum of sine waves at the network
frequency and multiples thereof. Each multiple is a harmonic of the signal that is
characterized by its frequency, amplitude, and phase dierence with respect to
the fundamental frequency (network frequency).
An interharmonic occurs when one of the frequencies of the sine waves is not a
multiple of the fundamental frequency.

this mode, the 8345 detects:
■
Slow variations
■
Rapid variations and interruptions
■
Voltage dips
■
Temporary voltage swells
■
Transients

2. Select the Congure monitoring option.
The conguration window will open with 5 tabs:
• Monitoring
• Slow variations thresholds
• Interruptions and Rapid Voltage Changes (RVC)
• Voltage Dips and Swells
• Transients
3. In the Monitoring tab, indicate the nominal voltage, the frequency, and the
name of the le that will contain the monitoring recording.
4. In the Slow Variations Thresholds tab, the maximum variations of the
frequency and the voltages are already specied for one week and the
duration of the monitoring recording, per the standard. You can modify the
values or add quantities to monitor.
5. In the Interruptions and Rapid Voltage changes (RVC) tab, keep
the preset values or modify them. The values specify the duration of
interruptions and rapid voltage changes (RVC), which are slower than
transients.
6. In the Voltage Dips and Swells tab, modify or keep the preset values that
specify the levels and durations of the voltage dips and swells.
The Transients tab is used to congure a search for transients (see § 3.4.5).
1. Press OK to conrm the conguration and transfer it to the instrument.
2. Then, start the monitoring recording on the instrument by specifying its start
