CSS / Container Substation

The substation is a compact enclosure consisting of MV switchgear, a transformer and an LV switchboard located in three separate compartments. They are segregated from each other by means of partitions in order to ensure personnel safety.

The equipment can be operated and maintained through lockable doors provided for each compartment to maximise security. The complete substation is assembled and factory ready to minimise the time taken and the cost of site installations.

COMPACT SUBSTATION

A compact substation (CSS) is a type of power distribution substation that is designed to be more compact and portable than traditional substations. It combines various electrical components in a single enclosure, making it easier to install and transport.

Some key features and components commonly found in compact substations include:

Enclosure:
Compact substations are housed in a weatherproof and robust enclosure. This enclosure is typically designed to be compact, offering a smaller footprint compared to conventional substations.
Transformers:
Compact substations include transformers for voltage transformation. These transformers can step up or step down the voltage as required by the specific application.
Switchgear:
Switchgear components such as circuit breakers, switches, and fuses are integrated into the compact substation. These components are essential for controlling and protecting the electrical distribution system.
Protection and Control Equipment:
Compact substations often incorporate protection and control devices, including relays and monitoring equipment. These devices ensure the safe and reliable operation of the substation and the connected electrical equipment.
Busbars and Connections:
Busbars provide a way to distribute electrical power within the substation. The compact design usually involves well-organized busbar systems to minimize space requirements.
Lightning and Surge Protection:
To protect the substation and connected equipment from lightning and surge events, compact substations may include lightning arrestors and surge protection devices.
Ventilation and Cooling Systems:
Adequate ventilation and cooling systems are integrated to dissipate heat generated by the electrical components during operation.

Compact substations find applications in various settings, including urban areas with limited space, temporary power installations, industrial facilities, and renewable energy projects. Their design allows for quick installation and easy relocation when needed. Additionally, compact substations are often pre-assembled and tested in a factory before being transported to the installation site, reducing on-site construction time and costs.
