Power quality

Individual & total harmonic distortion for voltage and current up to the 50th order. The harmonic content is represented like even, odd and total.
CPU2 option - the co-processor board performs the simultaneous high-resolution sampling of voltage and current, allowing the cycle-by-cycle power analysis for 50/60 Hz lines. The CPU2 board supports different application like: VDROP, VMAX, WCAP... (see below). The instrument with CPU2 board performs at the same time the wattmeter functions, the harmonic analysis, the basic recording function and the selected cycle-by-cycle power analysis function.
VDROP option - sags & swells detection on L-N voltages with half cycle resolution (10ms @ 50Hz). Pre- and post-trigger logging (100+100 half cycles RMS values). The detected events are recorded. This data is viewed on the PC according EN50160 standard.
VMAX option - two functions are selectable: VDROP (previous paragraph) and Min/Avg/Max values calculation and recording with one cycle resolution (20ms @ 50Hz). This function allows to record up to 10 parameters selected among voltage, current, power, PF and frequency. The data is viewed on the PC according EN50160 standard.
WCAP option - advanced waveform capture function o currents and L-N voltages. In case of single trigger the threshold mode is programmable as voltage or current; in dual trigger the threshold mode is fixed including both parameters (voltage¤t), allowing the waveform capture in case threshold overcoming both for voltage and current.
The instrument can store up to 10 + 200 waveforms before and after a threshold overcome, with a resolution from 8 to 32 samples (depending on the number of waveforms). The WCAP option includes a second selectable function: Min/Avg/Max values calculation and recording (see previous paragraph).

2 MB non-volatile memory for data storage.
Up to 10 programmable recordings with different start and stop time. Different type of recordings can be chosen:
- import/export active, reactive and apparent power demand with programmable average time.
- instantaneous read values selected between the main parameters. The recording interval time is programmable between 1 and 9999 seconds.
- instantaneous min/max values measured during the recording interval time. The recording interval time is programmable between 1 and 9999 minutes.
- voltage and current harmonic values measured during the recording interval time. The recording interval time is programmable from 1 to 60 minutes.
Time-of-Use (TOU) programmable data recording. The TOU function stores the energy consumption in different registers according the programmed time-scheme. A group of 120 registers give the situation of the previous and present day, and of the previous and present month. This feature is designed to fit different tariff structures. It’s possible to program up to 10 daily tariff schedules containing up to 3 tariffs and 8 tariff changes. Each schedule can be assigned to the days of the week and months as requested. Up to 20 holidays can be assigned to the lowest tariff. A diagnostic algorithm checks and notifies any setup overlapping.
Event, alarm and digital outputs ON/OFF recording. The instrument records the status change of 8 programmable set points, the digital outputs ON/OFF and the instrument supply ON/OFF. All the events are integrated by date and time reference.
The CPU2 option includes 1 MB non-volatile data memory. Depending on the CPU2 configuration the following information (already described in the “Power quality” paragraph) can be recorded:
- sags and swells events (VDROP option). The occurring dips and overvoltage over a programmable threshold are detected and the instrument records the date and time of the event, the lenght and the RMS value of 100+100 half-cycles before and after the event.
- min / avg / max values of the main measured parameters with continuous sampling and 1 cycle minimum resolution for RMS calculation. The resolution is programmable between 1 and 99 cycles to simulate the recorder response time as needed. The programmable average time defines the time interval between recordings.
- more than 200 waveforms when a programmable --threshold is overcome (WCAP option). The instrument records up to 10 + 200 waves before and after the trigger, with the time reference. The resolution is programmable from 8 to 32 samples / cycle.
