Medcal STII - Three phase network analyzer w/ MicroFlex Current Probes.
The instrument is designed for Norwegian conditions and measures all parameters according to FoL.
The MEDCAL ST II three-phase network analyzer is the optimal solution for large-scale, distributed voltage quality recording solutions.
Medcal STII covers all the requirements of EN 50160, it records the most common disturbances: voltage dips and swells including voltage profiles, total demand distortion (TDD), voltage and
current harmonics and inter harmonics plus voltage flicker.
Additionally, it support all the common electric magnitudes: Voltage, Current, Frequency, Unbalance, Active, Reactive and Apparent Power as well as Active, Reactive and Apparent Energy. Cos(F)
is also recorded when possible.
If Cos(F) cannot be calculated the Power Factor is used instead.
MEDCAL STII is capable of storing more than six months of recorded data under normal conditions using the recommended default 10 minutes averaging period.
The instrument is equipped with an advanced dual power supply: one is powered via two independent high voltage safety leads and can accept AC voltage between 70 and 480VRMS as well as DC voltage between 100 and 600VDC and the other obtains power from its USB host (PC) with reinforced isolation.
It is possible to measure and download data without feeding the equipment with mains voltage by just using the USB cable.
In case of interruption the instrument keeps recording and measuring for 10 seconds, and after this period the recordings are saved into the internal memory.
The recording will resume automatically once the power voltage returns.
Summary of main capabilities recorded phenomena:
- Voltage and current RMS max, average and minimum values
- Voltage interruptions, dips and swells: time and duration of event
- Voltage and current harmonic distortion (UTHD and ITHD)
- Total Demand Distortion (TDD)
- Voltage and current harmonics and inter-harmonics up to 50th order
- Network frequency max, average and minimum values
- Active, reactive and apparent power and energy. Cos(F) and Power Factor
- Voltage flicker: Plt and Pst values
- Voltage and current unbalance
- Residual or fault current calculation
