WebApr 4, 2024 · PTs provide voltage signals for control circuits, such as automatic voltage regulators, reactive power compensators, and other control systems. These are used in testing high-voltage equipment, such as transformers and circuit breakers. Potential Transformers are used to measure the voltage and current during testing. WebNov 27, 2024 · The phasor or vector diagrams for a transformer on resistive, inductive, and capacitive loads are drawn by taking flux Φ as the reference. Let, V 1 = Primary supply voltage. E 1 & E 2 = Primary and secondary induced emf's. I o = No-load primary input current. I 2 = Primary current. I 2 = Secondary current.
WebConcept: As can easily be seen by the phasor diagram, no Load current is (I o) is divided into 2 components: 1) Reactive or magnetizing component Im, It is in quadrature with the … WebSaturation refers to the nonlinear relationship between the magnetizing force and the resultant flux density for a ferromagnetic material. The d-axis of the SYNCREL, because it is dominated by iron, does show saturation in normal operation. Figure 8.10 shows the flux versus current relationship for the d-axis of an axial laminated SYNCREL. 9 Note that for …
