Current Transformer Simulation

Current transformer simulation models how a CT converts primary current (Ip) to secondary current (Is), including burden, ratio error, phase displacement, and saturation behavior, enabling protection engineers to evaluate relay performance and fault response in power systems. The governing relationship is defined by the CT ratio (Ip / Is), but actual performance depends on excitation current, phase displacement, and distortion that occur when the CT operates outside ideal conditions. Under increasing burden or fault current, the CT no longer reproduces current linearly. Secondary current deviates from the expected ratio, phase angle error increases, and waveform distortion appears as the core…

Types of Short Circuit Faults in a Power System

There are four short-circuit faults in power systems: single-line-to-ground, line-to-line, double-line-to-ground, and three-phase faults. They differ in how conductors contact each other or ground, affecting fault current magnitude, system stability, and protection response requirements during operation. Single Line-to-Ground Fault This is the most common short circuit in three-phase power systems. It occurs when one energized conductor unintentionally makes contact with earth, creating a fault path to ground. Line-to-Line Fault This fault occurs when two energized conductors come into direct contact, allowing current to flow between phases without involving ground. Double Line-to-Ground Fault A double line-to-ground fault occurs…

Capacitor Voltage Transformer Explained

A Capacitor Voltage Transformer (CVT) steps down high-voltage transmission levels for protection, metering, and control. Using a capacitive divider and electromagnetic unit, CVTs provide accurate, safe monitoring in power systems and substations. How a Capacitor Voltage Transformer Works A Capacitor Voltage Transformer (CVT) is a type of voltage transformer used in high-voltage (HV) substations to step down transmission line voltages for metering and protection purposes. It utilizes a capacitive voltage divider in conjunction with an electromagnetic voltage converter to provide a scaled-down replica of the HV signal, making it suitable for use in relay and measurement equipment. A CVT…
