Line Protection with Impedance Relays01:27

Line Protection with Impedance Relays

120
Coordinating time-delay overcurrent relays in complex radial systems and directional overcurrent relays in multi-source transmission loops can be challenging. Impedance relays address these issues by responding to the voltage-to-current ratio, specifically measuring the apparent impedance of a line. These relays become more sensitive during faults as current increases and voltage decreases, thereby reducing the apparent impedance.
Under normal conditions, low load currents keep the measured...

Energy Stored In A Coaxial Cable

1.6K
A coaxial cable consists of a central copper conductor used for transmitting signals, followed by an insulator shield, a metallic braided mesh that prevents signal interference, and a plastic layer that encases the entire assembly.
In the simplest form, a coaxial cable can be represented by two long hollow concentric cylinders in which the current flows in opposite directions. The magnetic field inside and outside the coaxial cable is determined by using Ampère's law. The magnetic...

Power System Three-Phase Short Circuits

132
Determining the subtransient fault current in a power system involves representing transformers by their leakage reactances, transmission lines by their equivalent series reactances, and synchronous machines as constant voltage sources behind their subtransient reactances. In this analysis, certain elements are excluded, such as winding resistances, series resistances, shunt admittances, delta-Y phase shifts, armature resistance, saturation, saliency, non-rotating impedance loads, and small...

Induced Electric Fields: Applications

1.8K
An important distinction exists between the electric field induced by a changing magnetic field and the electrostatic field produced by a fixed charge distribution. Specifically, the induced electric field is nonconservative because it does not work in moving a charge over a closed path. In contrast, the electrostatic field is conservative and does no net work over a closed path. Hence, electric potential can be associated with the electrostatic field but not the induced field. The following...

Charging Conductors By Induction

8.0K
The Earth is a good conductor of electricity, and it is so big that it can be considered an infinite source or sink of charges. It can easily exchange charges with any matter.
Generally, conductors like metals do not allow any excess charge to be present on them. Any excess charge added to metals easily flows away, for example, when a metal is placed on the Earth. This process is called earthing.
However, conductors can be charged by a process called induction. For example, consider charging a...

Three-Phase Short Circuit—Unloaded Synchronous Machine

194
Conducting a three-phase short circuit test on an unloaded synchronous machine helps understand its impact on the system. The AC fault current's oscillogram, with the DC offset removed, reveals that the waveform amplitude decreases from an initially high value to a steady-state level for one phase of the machine.
This behavior occurs due to the magnetic flux produced by the short-circuit armature currents. Initially, these currents follow high-reluctance paths but eventually shift to...

Area of Science:

  • Electrical Engineering
  • Materials Science
  • Power Systems

Background:

  • Partial discharge (PD) detection is crucial for monitoring insulation health in medium- and high-voltage power cables.
  • Existing methods require effective sensors for accurate defect tracing and aging assessment.

Purpose of the Study:

  • To experimentally evaluate three PCB-based inductive sensor topologies (spiral, non-spiral, meander) for PD detection.
  • To assess sensor performance in different positions relative to a defective power cable.

Main Methods:

  • Simulation and experimental characterization of sensor electrical circuits and quality factors.
  • Testing three PCB sensor types on a defective medium-voltage AC (MVAC) cable in three positions (P1, P2, P3).
  • Comparative analysis with a commercial high-frequency current transformer (HFCT).

Main Results:

  • All sensors detected PD as damped sine wave signals with similar frequencies and durations.
  • The non-spiral inductor exhibited the highest sensitivity (e.g., ~500 mV in P1), while the meander sensor showed the lowest (~80 mV in P1).
  • The non-spiral sensor's high sensitivity is attributed to its low resistivity, leading to favorable quality factor and SFR.

Conclusions:

  • PCB-based non-spiral inductive sensors are highly effective for partial discharge detection in power cables.
  • Sensor placement significantly impacts detection sensitivity.
  • The non-spiral design offers a promising alternative for power cable insulation monitoring.
