IV Model 8345
17.8.2 Standard IEC 61000-4-30, Class A
All of the measurement methods, measurement uncertainties, measurement
ranges, aggregations of measurements, flagging, and markings comply with the
requirements of IEC 61000-4-30, edition 3.0, for instruments of Class A.
The 8345 performs measurements and calculations for the following.
■
Line frequency over 10 s
■
Amplitude of the voltage for 10/12 cycles, 150/180 cycles, 10 min, and 2 h
■
Voltage unbalance for 10/12 cycles, 150/180 cycles, 10 min, and 2 h
■
H armonics of voltages for 10/12 cycles, 150/180 cycles, 10 min, and 2 h
■ Interharmonics of voltages for 10/12 cycles, 150/180 cycles, 10 min, and 2 h
■
Minimum and maximum values of the voltage (Under/Over deviation)
■
Flicker over 10 min and 2 h
■
Detection of voltage dips, swells, and interruptions, in amplitude and duration
■
Mains signaling voltages (MSV)
■
Rapid voltage changes (RVC)
■
Amplitude of the current for 10/12 cycles, 150/180 cycles, 10 min, and 2 h
■
Current unbalance for 10/12 cycles, 150/180 cycles, 10 min, and 2 h
■
Harmonics of currents for 10/12 cycles, 150/180 cycles, 10 min, and 2 h
■
Interharmonics of currents for 10/12 cycles, 150/180 cycles, 10 min, and 2 h
All measurements are made for 10/12 cycles and synchronized with UTC time
every 10 min.
Then, they are aggregated to 150/180 cycles, 10 min, and 2 h.
