Substations

Substations may be attended (or manned) or unattended (or unmanned).

Substations may be remotely controlled.

Safety enclosed boards are used for most new installations. Common terms used to designate equipment of this type are metal-enclosed switchgear and metal-clad switchgear.
Most safety enclosed boards are of the unit or sectional type. They consist of a combination of the desired number and type of standardized unit sections.
Each section is a standard factory-assembled combination of a formed steel panel and apparatus mounted on a steel framework.

Safety enclosed switchgear may be classified with respect to purpose of application as follows:
1. General medium- or high- voltage switchgear
2. Primary unit substations
3. Rectifier unit substations
4. Secondary unit substations or power centers
5. General low-voltage switchgear
6. Low-voltage distribution switchboards
7. Motor-control-center switchboards

[American electricians’ handbook]

Medium-voltage switchgear (Fig. 4.115) provides for the required control and metering equipment for generators, transformer supply circuits, feeders, large motors, etc., for systems with voltage up to 15,000 V. A large variety of standardized units is available

They are usually installed on the load side of MV/LV transformers or generators.
These assemblies include one or more incoming units, bus ties and a relatively reduced number of outgoing units.
There are also present measuring instruments and other switching and control equipment.
These assemblies have a sturdy structure to withstand the electrodynamic stresses and the weight of big sized apparatus.
As a matter of fact peculiar characteristics of the power center are high rated currents and shortcircuit currents.
The constructional type is a cubicle structure, with metal enclosure and sections divided into compartments with selective access.

Такие устройства обычно подключают на стороне нагрузки СВ/НВ трансформаторов или генераторов.
В их состав входят один или несколько блоков ввода, шины и относительно небольшое число блоков вывода.
В состав комплектного устройства первичного распределения электроэнергии входят также измерительные приборы, коммутационные устройства и средства контроля состояния.
Данные комплектные устройства имеют прочную конструкцию, способную выдерживать электродинамическое действие токов и вес крупногабаритной аппаратуры.
Центры распределения электроэнергии характеризуются высокими номинальным током и током короткого замыкания.
С точки зрения конструктивного исполнения они представляют собой многошкафное комплектное устройство в металлической оболочке, состоящее из секций, каждая из которых разделена на отсеки с независимым доступом.

Unit substations are used indoors and outdoors.

Many substations are unattended and use automatic or remote control.

If purchased power is to be used, then only the transformers, substations and distribution facilities need be provided.

Much needs (or remains) to be done to satisfy these requirements.

We provide such units exactly where they are wanted.

This process involves (or presents) ( some) difficulties (or problems).

Each new problem poses its own unique challenges.

The location of new substations has been a problem because of space restrictions.
