Voltage Eligibility
The DPMS XPQ-G can take the statistics of voltage eligibility, then give out
a great amount of data.
Eligibility = (1-overlimit time/Measuring time)*100%
The upper and lower limits of voltage can be set according to the user.
When voltage is out of range, it is not eligible. Three limitations of voltages of
the phase or line can be set respectively. The format of the setting value and
communication value is the same. They are all set according to input voltages.
For example, if the PT used is a 10000/100 PT, the high limit of voltage is set as
10300V, then the setting value is 10300÷(10000/100)=103V. Then according to
the relationship between the communication value and numerical value , U=Rx
X (PT1 / PT2) /10, so the value to be written, Rx is 103*10=1030. Setting by
pressing keys should use the same value.
Voltage eligibility consists of running time, channel eligibility and eligible
time. In order to find and analyze, it is divided into real time, statistics, and
freezing zone. Please refer to the address table for more details. The format of
eligibility is 99.9999999%.
Voltage eligibility can be frozen and cleared.
Here is an example:
