Training Course on Substation

Introduction

Where a large number of electric power produced by a special plant that’s called electricity generating station. Where supply voltage changed by a special apparatus like a transformer, and some other switchgear apparatus called substation. High electric power transmitted by three-phase three-wire from one place to another place or substation that’s called transmission line. The power system consists of three main parts like generation, transmission, and distribution.

These transmission lines may be found overhead or sometimes in the underground, and, combined, transmission lines, and distribution lines make up it is commonly called the grid. The transmission line and distribution line are two separate stages on the grid.

The transmission line refers to the part of electricity delivery that moves more electricity from the generation substation over long distances to substations closer to areas of electricity demand. An advanced training course on substation is going to Bangladesh Automation Technologies. The substation course is crucial for the industry.

HT Panel Board to Describe

HT panel stands for High Tension panel HT panel are compact outdoor type systems, which are broadly used in substations. HT panel consists of Circuit Breakers, switches, fuses, indicators, HT panels protected by the earth, but a lightning arrestor placed the outside of the panel, which protects the equipment from surge voltage.

HT panel is a metal enclosure fitted with HT Circuit Breakers, relays & other metering equipment that used to receive power 33KV or 11KV from one or more sources, and distribute the power through its outgoing feeders. You will get vast knowledge about the HT panel board to describe from this training institute.

The outgoing feeder can be one or more it depends on the load. HT panel is installed in substations of commercial complexes, industrial purposes, residential colonies, factories, schools, hospitals, etc. The main function of the HT panel such as

• To make and break HT supply (or switch on or switch off supply),
• To receive and distribute HT supply,
• To protect against faults,
• To provide metering to monitor various parameters.
• HT panels also used to monitor supply systems.

LT Panel Board to Describe

LT Panel stands for Low Tension panel. It is an electrical distribution board that receives power from the transformer and distributes power to the various electronic devices and distribution boards. These types of panels used in industries both for internal and external use and, therefore, they are quite complex to withstand different climatic conditions.

Actually, LT panels are designed to work with low electricity consumption that makes them cost-effective. LT panel consists of a switch, circuit breaker, indicator, ammeter, and voltmeter.

LT panel is a metal enclosure fitted the power distributed in different machines, sections, various purpose, Low Tension switchgear consists of the main incoming circuit breaker (MCB, MCCB, and ACB). As per the capacity of the Transformer, Bus-bars, Outgoing Circuit Breakers MCCB, and MCB.

Bangladesh Automation Technologies giving you a learning opportunity about the training course on substation there is a lot of substation equipment at this institute and skilled trainer. This trainer will help you to gather vast practical knowledge about substation. You will get vast knowledge about the LT panel board to describe from this training institute.

Transformer Describe

The transformer is a static electromechanical device the transformer changes the voltage level from low voltage to high transmission voltage or high voltage to low electric power according to the requirement. Usually, electrical power is generated at 11Kv. For economic reasons, AC power is transmitted at very high voltages like 440 kV over long distances.

Therefore a step-up transformer used at the generating stations. Now for safety reasons the voltage is stepped down to different levels by using a step-down transformer at various substations to feed the power to the different locations. And thus the utilization of power is done at 400/230 V. Transformer consist of various component such as

• Magnetic circuit or magnetic core
• Electrical circuit
• Dielectric circuit
• Tanks and accessories
• Transformer Bushing
• Breather

Types of the Transformer

There are various types of transformer depends on the work and construction which is below.

1. Position of the windings concerning the core

• Core type
• Shell type

2. According to the transformation ratio or number of turns in the windings

• Step up
• Step down

3. Types of services

• Power transformer
• Distribution transformer
• Instrument transformer
• Current transformer
• Potential transformer
• Auto-transformer

4. Based on the supply

• Single-phase
• Three-phase

5. Based on cooling

• Natural Air cooling (NA)
• Air Forced (AF)
• Oil Natural Air Natural (ONAN)
• Oil Natural Air Forced (ONAF)
• Oil Forced Air Forced (OFAF)
• Oil Natural Water Forced (ONWF)
• Oil Forced Water Forced (OFWF)

The transformer is the important equipment in the power system transformer mandatory for every Generating station, Substation, or Distribution. So you will get a real and clear concept by the training course on substation this course will be beneficial for your industrial work.

PFI Panel Board Calculation

PFI stands for Power Factor Improvement, the cosine of the angle between voltage and current is called power factor. The power factor always in an AC circuit. The maximum value of the power factor is one, and the minimum value is zero. The power factor of the system decreased due to the inductive type load of different industries and big apartments.

PFI Plant for improving the low Power Factor of the system. We have microprocessor-based PFC (Power Factor Correction) relay up to 24 stages. The Capacitors we use are of different ratings such as 2.5, 5, 10, 20, 25, KVAR, etc.

And corresponding Magnetic Contactor for suitable stepping of the Capacitor bank. The power factor sometimes expressed as a percentage. PFI panel board calculation is straightforward, so the power factor is the ratio of working electric power, measured in kilowatts (kW). Apparent power, measured in kilovolt amperes (kVA).

Calculation

The substation is a significant part of the power system electric power become step up, and step down in substation. A substation may be a generation substation, transmission substation, and distribution substation.

Bangladesh Automation Technologies providing training courses on substation we have a good classroom, better environment, skilled trainer, and more substation equipment. This training institute played a leading part, and it is the best training institute in Bangladesh.
