Load Curve and Load Duration Curve

Load Duration Curve in Power Station

Load duration curves are used in power stations to illustrate the relationship between generating capacity requirements and capacity utilization. A load duration curve (LDC) is similar to a load curve

Transformer Bushing Types

Transformer Bushing Types : RIP Bushing vs OIP Bushing

Transformer bushing types are categorized based on their material, manufacturing, and design mainly into the following types: OIP (Oil-Impregnated Paper) Bushing RIP (Resin Impregnated Paper) Bushing RIS (Resin Impregnated Synthetic)

Properties of Good Transformer Oil

Even though the basic functions of the oil used in transformers are heat conduction and electrical insulation, there are many other properties which make a particular oil eminently suitable. Properties of good transformer

why we need power system protection

Why we need Power System Protection?

In this article, you will learn the importance of protection in the modern power system and why we need power system protection. It is fair to say that without discriminative

Low voltage Switchgear

Low Voltage Switchgear

As per IEC 60947, switchgears with rated voltages up to 1000 V ac and 1500 V dc are termed as low voltage switchgear. The term ‘switchgear’ is a generic term

substation earthing

Substation Earthing System Design

We have already given an introduction to substation earthing system in an article published earlier. Today we are going to discuss the design of substation earthing system. Before 1960s the


IEC 61850 – Features and Advantages

IEC 61850 is a standard for the design of electrical substation automation. It has been defined in cooperation with manufacturers and users to create a uniform, future-proof basis for the

Solid State Relay

Solid State Relays (Static Relays)

What is a Static Relay? There are two basic classifications of relays – Electromechanical Relays and Solid State Relays (Static relay). One main difference between them is electromechanical relays have

all day efficiency of transformer

All Day Efficiency of Transformer

Definition The ratio of output in kWh to the input in kWh of a transformer over a 24-hour period is known as all day efficiency. ηall-day = Output in kWh
