Modelling of non-conventional instrument transformers (NCIT) by FEM [PDF]
, 2018 In this paper, we have shown that the proposed non-conventional instrument transformer using magnetic shape memory (MSM) alloys can be used for current measurement in high voltage overhead transmission lines.

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 ...

Evaluation of Voltage Transformers’ Accuracy in Harmonic and Interharmonic Measurement
IEEE Open Journal of Instrumentation and Measurement, 2022 The measurement of Power Quality (PQ), generally performed at Low Voltage (LV) level, is gaining more and more importance also at the Medium Voltage (MV) level, due to the increasing presence of switching power converters (both loads or generators ...

Development of electro-optic polymers for high-voltage instrument transformers [PDF]
, 1994 This paper describes some poled electrooptic bulk polymers (EOP) of the guest/host type having a cured epoxy resin as the host. The electrooptic polymers of typical dimensions 13 X 13 X 3 mm are characterized with respect to application as Pockels ...

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 ...
