Class A according to standard IEC 61000-4-30, Edition 2

Class A is defined in the international standard IEC 61000-4-30, which establishes a correspondence between the parameters of quality of electric energy, accuracy requirements and standards, enabling comparison of results obtained by the different measuring means.
PW3198 corresponds to the class A standard IEC 61000-4-30, edition 2. The device can perform measurements in accordance with the standard, including long calculations without intervals, event detection such as dips, emissions and short-term voltage cuts. Time synchronization is also possible using an optional GPS module.

Safety category CATIV-600V

PW3198 meets safety category CATIV-
600V and can also be safely used on the incoming
lines of single-phase and three-phase power systems.

Easy to set up – simply select the type of measurement, and the PW3198 will do the rest.

The basic measurement error (50-60Hz)

One of the best values of the basic measurement error in the world. Extremely high measurement accuracy without the need to change ranges.

Transient overvoltage.

Transient overvoltage may be measured in the voltage range up to 6000 V and with a minimum duration of 1 microsecond (2∙106 samples / s).

High-order harmonic

PW3198 – this is the first
analyzer of
electric energy quality, which
is capable of measuring
high-order harmonics
up to 80 kHz.

PW3198 will not miss the time of the accident in the system

PW3198 can simultaneously shoot waveform and control harmonics parameters, identifying emergency modes. If you have any problems at your facility with the equipment and switchgear PW3198 system will quickly find and eliminate the cause. You can rest assured that the PW3198 will be able to control all the necessary characteristics of your power supply.

Simultaneous measurement of all parameters

All the necessary information can be quickly obtained by switching pages

Simply connect to the line, a condition of which it is necessary to control and PW3198 will simultaneously measure all the parameters of power and harmonics. You can immediately view the information, switching pages.

Display of digital values. Indication of parameters such as voltage, current, power, power factor, and integral power in a single window.

Reliable detection of power abnormality (events)

To detect anomalies in the power supply system there is no need to repeatedly perform the measurement under various conditions. PW3198 can constantly monitor the power supply system and is guaranteed to detect all types of anomalies, for which this feature is enabled.

Transient (impulse) overvoltage

Transient overvoltage is a result of lightning and transient processes, such as switching contacts of circuit breakers. They often cause sharp fluctuations and high voltage peaks.

DF1 Switching windows in one touch

Waveform display. Displaying waveforms and current channels 1-4 above each other in one window.

DF1 Switching windows in one touch

4-channel waveform display.
Separate display of waveforms and current channels 1-4.

DF2 Switching windows in one touch

Display in vector form. The display of modified value and vectors of voltage and current for each harmonic.

DF2 Switching windows in one touch

Display of harmonics spectrum. Display of effective value and phase shift angle of harmonics from 0 to 50-th order in the form of graphs and numerical values.
Voltage dips. The voltage falls for a short time as a result of high current, e.g., at engine start.
Interruption. Power supply immediately stops for a short or long period of time as a result of disabling the power line due to lightning or the circuit breaker due to short circuit.
Fluctuations of the frequency. An excessive increase or decrease in load leads to instability of the generator and its frequency fluctuations.

Harmonics are generated by semiconductor inverters installed in the equipment connected to the system. They lead to a distortion of the voltage and current form.

Voltage surges are the result of lightning or disabling or enabling of the power lines.

Inrush current.

The sharp increase in current at the time of switching engines and other devices.

High-order harmonics. Voltage and current waveform is distorted by noise components produced by semiconductor converters or impulse power supply of electronic equipment.

The asymmetry.

Increase or decrease in load connected to each of the phases of a three phase supply system, or unbalanced operation of the equipment results in the load of one of the phases becoming excessive. This leads to distortion of current voltage waveform, voltage drop, or the appearance of the negative sequence voltages.
