A portable system for phasor measurment units (PMU) calibration in high-voltage substations
Measurement: Sensors, 2021 This paper presents the advances in the development of a portable PMU standard for online calibration of PMUs installed in high voltage substations. This system is intended to be connected in parallel with the PMU under test, without disconnecting it from the network. Current and voltage sensors do not need to interrupt the service.

Tool for testing of phasor measurement units: PMU performance analyser
IET Generation, Transmission & Distribution, 2015 Phasor measurement units (PMUs) are one of the key sensor technologies for real‐time wide area monitoring to realise the smart power grid vision. Before deploying the PMUs, it is important to test and validate performance of this sensor to ensure high reliability and accuracy under different operating scenarios of the power system. However, PMU testing
