Understanding Transformer Testing-09 Important electrical tests

by

Transformer testing encompasses a range of tests and procedures aimed at evaluating the performance, safety, and reliability of transformers. These tests are conducted during manufacturing, first time installation/charging, and regular maintenance to detect potential issues and ensure compliance with industry standards. Different types of tests for Transformer Testing During pre-commissioning stage of a transformers, broadly … Read more

Star to delta transformation

by

Before we explain Star to Delta transformation and Delta to Star transformation, let us first understand these connections separately: Star Connection (Y Connection) Star connection is in shape of Y, therefore it is also called Y connection. In a star connection, three windings or terminals of the three-phase system are connected together at a common … Read more

TNC (Trip and close) switch (52 CS) wiring diagram: Easy learning

by

Introduction (PC-https://www.industrybuying.com/) TNC Switch (Trip and close switch) as the name indicates is used to manually trip and close the circuit breaker. The three positions in the TNC switch wiring diagram as shown below are called Trip, Neutral and close. There are some NO (Normally open) contacts, some NC (Normally close) contacts and some spare … Read more

What is RTU in SCADA? Its 03 important benefits.

by

“RTU” stands for “Remote Terminal Unit.” It is a device used in SCADA (Supervisory Control and Data Acquisition) systems to collect data from sensors and equipment in the field. They are responsible for transmitting this data back to the central SCADA system for monitoring and control purposes. They play a crucial role in enabling real-time … Read more

What is SCADA and how it works? 07 Key Components.

by

Introduction SCADA stands for Supervisory Control and Data Acquisition. It is a system of hardware and software elements which allows organizations and industries to control and operate processes remotely, gather data, and monitor real-time information. SCADA systems are commonly used in industries such as power generation and distribution, water and wastewater treatment, oil and gas … Read more

What is the principle of microgrid?

by

Microgrid are self sufficient and localized energy systems that can operate independently or in conjunction with the main grid. They are designed to generate, distribute, and control the flow of electricity within a limited geographical area, such as a community, university campus, hospitals, military base, or industrial complex. They can incorporate various energy sources, including … Read more

PLCC -What is the work of Power line carrier communication? Its 04 Important components.

by

PLCC-Power line carrier communication is used for telecommunication between substations, it is also used for tele-protection and conductors of transmission lines are used for these purpose. It is usually used for high voltages, such as 132 kV, 220 kV, 400 kV etc. Two substations are connected using transmission lines (conductors) and these conductors are also used for … Read more

220/132 KV Grid Substation Overview

by

A 220/132 KV Grid Substation means that input voltage in the substation will be 220 Kilo-volts(KV) and the transformer installed in the substation will step down this voltage to 132 kilo-volts(KV) for onwards transmission. Usually there will be two separate switchyards of 220kv and 132kv voltage level and equipment of corresponding voltage levels like CVT,C.B,C.T, … Read more

Complex power

by

What is complex Power? Before we understand complex power ,let us first understand what is Power. Electrical power is the rate at which electrical energy is transferred or converted in an electrical circuit. It is a measure of how quickly electrical work is done or how quickly electrical energy is consumed or produced. Real electrical … Read more
