Toward the Standardization of Limits to Offset and Noise in Electronic Instrument Transformers
Sensors, 2020 The scenario of instrument transformers has radically changed from the introduction of the Low-Power version, both passive and active. The latter type, typically referred to as Electronic Instrument Transformers (EITs), has no dedicated standard within ...

Smart Characterization of Rogowski Coils by Using a Synthetized Signal
Sensors, 2020 With the spread of new Low-Power Instrument Transformers (LPITs), it is fundamental to provide models and characterization procedures to estimate and even predict the LPITs’ behavior. In fact, distribution system operators and designers of network models

The effect of AM noise on correlation phase noise measurements [PDF]
, 2006 We analyze the phase-noise measurement methods in which correlation and averaging is used to reject the background noise of the instrument. All the known methods make use of a mixer, used either as a saturated phase detector or as a linear synchronous ...

Temperature characterisation of an optically-interrogated Rogowski coil [PDF]
, 2014 An investigation into the performance of an optically-interrogated Rogowski coil over temperatures up to 80 °C is presented. Preliminary thermal tests reveal that the sensor response is temperature-dependent and the measurement errors are increased at ...
