The principle of operation of line differential protection is same as transformer differential protection. The only difference is transformer differential protection uses only one differential relay whereas line differential protection… Read more »
In this post, we can learn the working and configuration of the Numerical Under voltage [27] /Over voltage [59] protection relay. These relays measure either phase-to-phase (Ph-Ph) or phase-to-neutral (Ph-N)… Read more »
Core Balance Current Transformer-CBCT: Core-Balance Current Transformer CBCT also called as Zero Sequence CT. In this type of CT a single ring or rectangular shaped core of magnetic material, encircles… Read more »
Potential or Voltage Transformer: The purpose of the Potential Transformer is to provide an isolated secondary voltage that is in-phase and exact proportionate representation of primary voltage. Potential Transformers are… Read more »
Electrical Interview Questions In this series of Interview questions, we will learn about the following major differences in Electrical Engineering. Major Differences in Electrical Engineering: 1. What are the major… Read more »
Differential Protective Relay is a protective relay that functions on a percentage or phase angle or other quantitative difference of two currents. Differential relaying provides selectivity by providing a zone… Read more »
