Characteristics and application scope of CA8334 harmonic analyzer

The CA8332 and CA8334 are compact, impact-resistant three-phase power quality analyzers. Its user-friendly design and intuitive user interface make measurement and use very simple and convenient. Not only can users measure the main power parameters (graphically) and real-time waveforms on the power grid, the CA8334 harmonic analyzer can also record and monitor the changing trend of power within a set time range.

The multi-task measurement system of the CA8334 harmonic analyzer can handle all changing amplitude value measurement, detection, continuous recording and other functions at the same time, and the display switching is not subject to any restrictions. Whether they are electrician technicians or professional engineers and other test and maintenance department personnel, they can use it for industrial, power or management measurement tasks to complete inspection, maintenance and inspection in single-phase, two-phase, and three-phase low-voltage power grid systems. .

The main measurement items of the CA8334 harmonic analyzer are:

- Measure two-wire, three-wire or four-wire power distribution systems with an effective value of AC voltage not greater than 480V (phase voltage) or 960V (line voltage).

- Measure the effective value of AC current, up to 6500A

- Measuring power grid systems with a frequency of 50Hz or 60Hz (10Hz to 70Hz).

- In star-connected networks, the neutral current is calculated via the phasor sum of the three-phase currents.

- Calculate the crest factor of current and voltage.

- Calculate the K-factor of the current (transformer related).

- Calculate short-term flicker values.

- Calculation of voltage and current imbalance (three-phase grid system).

- Measure the harmonic angles and ratios (regarding the fundamental wave value) of voltage, current, and power, up to the 50th order.

- Calculate all harmonic distortion rates.

- Measure the active, reactive and apparent power of each phase and the total value.

- Calculate power, change and tangent factors.

- Calculate the total amount of electricity generated and consumed within a certain period of time.

- Monitor the trend graph of any power parameter. The accumulation time can be set to a calculation period from 1 second to 2 hours, and the values ​​are stored in the instrument's memory.

- Record the time and characteristics of power grid interference: such as voltage rise, voltage sag, voltage interruption, power and harmonics exceeding the threshold setting value, etc.

- Detect voltage transients and disturbances and store corresponding waveform patterns.
