Specifications: Fluke 1760TR Three-Phase Power Quality Recorder

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, 2 h<
Triggered recordings	rms	Aggregation time is adjustable between 10 ms (1/2 cycle), 20 ms (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.

Input filter	Each channel is equipped with a passive low-pass filter, an anti-aliasing filter and a 16-bit A/D converter. All channels are sampled synchronously with a common quartz-controlled clock pulse. The filters protect against voltage transients and limit the signal rise rate, reduce high frequency components and especially the noise voltage above half the sampling rate of the A/D converter by 80 dB, thus achieving very small measuring errors in an exceptionally large amplitude range. This is also valid under extreme operating conditions like transient voltages at the output of converters.
