What is a Magnetic Circuit ?
The magnetic lines of forces follow a closed path. This closed path is called the magnetic circuit. In an electric circuit, the current follows a
Why is PT burden high Compared to CT burden?
The burden is the maximum load that we can connect to the secondary CT and PT. The burden of CT and PT are expressed in
What is CT Burden? CT Burden Formula
CT burden means the load connected to CT secondary. The load may be of the resistive type or of the inductive type. However, the load
Control Valve Positioner | Operating Principle & Its Types
A control valve positioner is a device that senses the signal from an instrument (controller) and the position of a valve stem. Its main function
Temperature Effect on Conductors, Semiconductors & Insulators
Temperature Effect on Conductors, Semiconductors & Insulators -The resistance of the conductor increase with an increase of temperature. Whereas, the resistance of semiconductors and insulators decreases
Uncertainty Calculations of Thermal Calibration
In this article, we will discuss the Uncertainty Calculations of Thermal Calibration. Uncertainty means how uncertain or certain we are about the result. No measurement
Control Valves Leakage Classifications
In this article, we will discuss the leakage & control valves leakage classifications. The main function of the control valves is to throttle the fluid
Basics of Globe Valves
Globe valves have a movable disk-type element and a stationary ring seat in a valve body. The valve stem moves a globe plug relative to the
Working of Rupture Disk
A Rupture Disk is a pressure relief device that actuates by static differential pressure between the inlet and outlet of the device causing bursting of a rupture disk.
