A Buchholz Relay is a gas-actuated safety device used in oil-immersed transformers to detect and protect against internal faults. It operates on the principle of gas accumulation or sudden oil flow caused by electrical faults inside the transformer. It is typically installed in the pipeline connecting the transformer’s main tank and the conservator.
A lightning arrester is a device that provides a low-impedance path to ground for lightning or transient overvoltages, effectively protecting the electrical system from high-voltage surges. It operates by limiting the voltage across its terminals to a safe value and shunting the excess energy to the ground. What is a Lightning Arrester? A lightning arrester,
An Energy Meter, also known as a watt-hour meter, is an electrical device used to measure the amount of electrical energy consumed by a residence, business, or electrically-powered device. The energy is typically measured in kilowatt-hours (kWh), which is the standard billing unit for energy consumption.
A Pitot tube is a commonly used variable head, fluid velocity measuring device. It is also called as Pitot static tube or air speed indicator (in aircraft). Figure 1: Pitot Tube.

A turbine flow meter is a device used to measure the flow rate of a fluid (liquid or gas) by converting the kinetic energy of the fluid into rotational motion of a turbine. The flow rate is proportional to the rotational speed of the turbine. Figure 1: Turbine Flow Meter.
The McLeod gauge is used for measuring pressures ranging from 0.01 micron to 1 mm of Hg. Figure 1: McLeod Gauge.
