EN50160 and ITIC, CEBEMA, ANSI와 같은 DISDIP tables에 의한 전력품질 통계

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.

In case of a power supply failure an internal battery maintains the supply for up to 40 minutes. Afterwards, or in case of discharged accumulators the Fluke 1760 is turned off and continues the measurements with the latest settings as soon as the supply voltage returns. The battery can be replaced by the user.

Fluke 1760 features LED indicators for the status of the 8 channels, phase sequence, power supply (mains or accumulator), memory usage, time synchronization, and data transfer.

• Permanent light: normal power supply from mains.

• OFF: supply via internal accumulator in case of a power failure.

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.

Uncertainty including the voltage sensors is in compliance with IEC 61000-4-30 Class-A. All voltage sensors are suitable for DC up to 5 kHz
