Overview of Measurement Functions

Statistical Evaluation

 

 Power quality statistics according to EN50160 and DISDIP tables like ITIC, CEBEMA, ANSI

Event List

 

 Dips, swells and interruptions are detected and stored in the event list. Also any trigger which fires generates an event added to this list.

 

 The Event list shows the exact time when the event occurred as well as the duration and magnitude. Sorting by several attributes of these events is possible to select one for further root cause analysis.

 

 RMS values, transients and fast transients can be stored if a trigger fires.

Continuous Recording

 

 Fluke 1760 records rms values together with corresponding minimum and maximum values for:

 

 • Voltage

 

 • Current

 

 • Power P, Q, S

 

 • Power Factor

 

 • kWh

 

 • Flicker

 

 • Unbalance

 

 • Frequency

 

 • Harmonics/Interharmonics

 

 continuously with the following time aggregations:

 

 Day

 

 10 min

 

 Free Interval, e.g.: 15 min, 2h

Triggered Recordings

rms:

 Aggregation time is adjustable between 10 ms (1/2 cycle), 20ms (1 cycle), 200ms (10/12 cycles) or 3 sec (150/180 cycles).

 

 Calculating rms values, Harmonics and Interharmonics is performed synchronous to the power frequency.

 

 Basic aggregation for harmonics and interharmonics is 200ms

Oscilloscope:

 Sample rate is 10.24 kHz for all 8 channels

Fast Transients:

 Sample rate is selectable from 100 kHz to 10 MHz for channel 1-4 FFT of Fast Transients

Mains Signalling

 

 Phases and N-conductor, Voltage and current

Online Mode

 

 Variable refresh rate. This feature allows verification of instrument set up and delivers a quick overview of oscilloscope, transients and events.
