Data Acquisition and Telemetering in Power Systems
To be able to manage and control a power system, the network engineer requires reliable and current information about the state of the network. He obtains this information from power flows, bus voltages, frequency and load levels along with the position of circuit breakers and isolators, the source of these data being in the power…

What is the difference between a Power transformer and a Distribution Transformer?
Introduction The transformer, in simple terms can be defined as the voltage regulator. It helps in stepping up and stepping down of the voltages. We all have seen transformers in our locality, where the current is passed from higher voltage to the lower voltages. In this blog, we will discuss about the differences between the…

Supervisory Control and Data Acquisition in Power Systems
The term supervisory control and data acquisition (SCADA) refers to the network of computer processors that provide control and monitoring of remote electrical or mechanical operation e.g. management of power distribution grid or the control of mechanical processes in a manufacturing plant. Typical the old SCADA systems would encompass computers and network links that manage…

Key Factors to Consider In Substation Design
Substations are the points in the power network where transmission lines and distribution feeders are connected together through circuit breakers or switches via busbars and transformers. This permits the control of power flows in the network and the normal switching operations for maintenance purposes. We discuss the key factors to consider when designing substations as…
