Functions:

ADS-13A

         Basic parameters measurement

         Basic parameters measurement could display voltage effective value, current effective value, frequency and other basic parameters and measurement waveform charts of voltage and current, and could display average value when measuring DC measurement source.

         Single-phase power measurement

         Single-phase power measurement could display apparent power, active power, reactive power, power factor. It could display DC power when measuring DC measurement source.

         Harmonic measurement of electric grid

         Harmonic measurement of electric grid is divided into harmonic measurements of voltage harmonic and current harmonic, which could mainly display the conditions of harmonic of 1-25 times, and it includes harmonic(or fundamental) time,harmonic real effective value,harmonic ratio (HR),total harmonic distortion (THD) and histograms of all harmonics.

         Oscillograph

         Oscillograph could display measurement wave forms of voltage and current， and it has three working states: running, keeping(that is manual catching), touching(that is automatic touching).

         Start-up measurement

         Startup measurement is used for measuring the shock of electric grid by startup and stopping of large-scale equipment (mainly current).

         Measurement record

         It could perform long-term monitoring record for voltage, current, frequency, power factor, voltage harmonic, current harmonic and other parameters, which could obtain max value, average value, minimum value of above parameters within record time and the change trend curves of all parameters within record time.

         Data analysis

         This function allows the user to upload the saving data to PC for all kinds of analyses.

         System updating

         This function allows the user to use computer to update the program of instrument.

 

ADS-13B

         Basic measurement

         It could measure voltage, current and frequency, and record change trend, the length of record time: 1 hour.

         Harmonic measurement

         It could measure three-phase four-line (three voltage, four current)harmonics of 1-25 times, and total harmonic distortion. It could record the harmonic change trend of certain time, the length of record time: 1 hour.

         Power measurement

         It could measure three-phase active power, apparent power, reactive power, power factor and etc of three-phase four-line power system, and record the change trend of three-phase active power, the length of record time: 1 hour.

         Unbalanced measurement

         It could measure unbalanced degree of three-phase four-line power system, and record change trend, the length of record time: 1 hour.

         Digital oscillograph function

         It could detect voltage and current wave form change conditions of three-phase four-line power system, and could record voltage or current wave form of certain moment.
