“…The Magnetic direction is from N pole to S pole, the magnetostrictive material will be magnetized to produce magnetostrictive phenomenon, and the measuring coil is used for magnetic induction intensity measurement [12]. However, in this method, the magnetic eld at the detection section is taken as the object of study, when a driving magnetic eld is applied to the magnetostrictive material, the measuring coil will generate a magnetic eld opposite to the change trend of the driving magnetic eld.…”

Under the role of applied magnetic field, different values and directions of magnetic induction intensity will be produced in different sections of the magnetostrictive material (Terfenol-D) in GMA (giant magnetostrictive actuator). When mono-coil is used to measure the magnetic induction intensity of the magnetostrictive material, measures must be taken to reduce the influence of the coil on the magnetic induction intensity. The method proposed in this paper can accurately measure the magnetic induction intensity of magnetostrictive material, it uses multi-coils to create the most suitable near-zero magnetic field at the detecting points, so as to reduce the influence of the coils on the magnetostrictive material itself and realize the accurate measurement of magnetostrictive material’s magnetic induction intensity.

Voltage and current measurements in high-voltage substations are fundamental for stable operation. Conventional instrument transformers (ITs) face challenges in gas-insulated switchgears (GISs), such as size, weight, accuracy limitations, and behavioral instability at abnormal voltages and currents. Non-conventional instrument transformers (NCITs) have emerged to address these issues, complying with International Electrotechnical Commission (IEC) standards and providing millivolt-level signals, enabling downsizing of GIS bays. The transition to digital substations, as mandated by IEC 61850-9-2, requires a shift from the conventional 110 V/5 A outputs to levels ranging from millivolts to volts. Electronic instrument transformers (EITs), compliant with the IEC 60044-7 and 8 standards, offer alternatives to conventional ITs with smaller sizes and wider frequency ranges. However, issues remain with EITs, including limited adoption, the necessity of separate power sources, and susceptibility to electromagnetic interference. Recent standards, transitioning to IEC 61869, focus on low-power instrument transformers (LPITs). Low-power voltage transformers (LPVTs) and low-power current transformers (LPCTs), designed with passive components, present potential solutions by directly connecting to merging units (MUs) for digital signal transmission. This review outlines the current status of various IT standards, covering conventional ITs, EITs based on IEC 60044-7 and 8, and LPITs based on IEC 61869-10 and 11. Advancements in sensor technology relevant to these standards are also explored. The paper provides insights into the evolving landscape of instrument transformers, addressing challenges and offering potential pathways for future developments in digital substations.
