Calibration of PMU
We can calibrate PMU (Phase Measurement Unit).
Purpose
PMUs measure quantities such as voltage, current, harmonics, frequency, and power against a common time reference, which means that measurements can be compared between substations in real time. This is valuable as it can be used for stability monitoring, faster analysis, and more efficient utilization of resources in the power grid. For these measurements to serve as a basis for decision-making, amplitude, phase angle, and frequency must be reported correctly; therefore, regular calibration is essential.
Method
We calibrate Total Vector Error (TVE), Frequency Error (FE) and Rate of Frequency Error (RFE). The uncertainty of TVE is 0.04%
Delivery
We provide calibration certificates in Swedish or English. You can download the certificate directly from website for calibration and receive all other information that you need regarding your measurement system. Please contact us if you have any questions or to discuss your needs.
