Anyone purchasing our Unilyzer 900 from this year and onwards will get the “Current trig” and “UBA” functions included in base configuration at no extra cost. Unilyzer 900c customers will get the “Current trig” function included.
Module UBA – UnBalance Advanced – is an enhanced unbalance measurement for voltage and current. UBA is the ideal tool for finding unbalance sources and planning for mitigation measures. Values stored are negative, positive and zero sequence with maximum and average values. The corresponding phase angles for the average sequences are also measured. The total scope of unbalance parameters included are:
- U2 Negative phase sequence/positive phase sequence, [%]
- U0 Zero phase sequence/positive phase sequence, [%]
- U2 max Maximum Negative phase sequence/positive phase sequence, [%]
- U0 max Maximum Zero phase sequence/positive phase sequence, [%]
- Positive phase sequence [V]
- Negative phase sequence [V]
- Zero phase sequence [V]
- Positive sequence phase angle [°]
- Negative sequence phase angle [°]
- Zero sequence phase angle [°]
- Maximum Positive sequence [V]
- Maximum Negative sequence [V]
- Maximum Zero sequence [V]
- I2 Negative phase sequence/positive phase sequence, [%]
- I0 Zero phase sequence/positive phase sequence, [%]
- I2 max Maximum Negative phase sequence/positive phase sequence, [%]
- I0 max Maximum Zero phase sequence/positive phase sequence, [%]
- Positive sequence [A]
- Negative sequence [A]
- Zero sequence [A]
- Positive sequence phase angle [°]
- Negative sequence phase angle [°]
- Zero sequence phase angle [°]
- Positive phase sequence [A]
- Negative phase sequence [A]
- Zero phase sequence [A]
The “Current trig” function enables to set the instrument to trig on specified current threshold. Usable for monitoring inrush events such as motor starts etc.
In addition to above the range of the 27-1950 DC clamp has been extended from 500A DC to 600A DC. Also note that on special request we can also supply DC clamps up to 1400 A DC.
