Standard braking and relay protection
The objective of relay protection is to quickly isolate a faulty section from both ends so that the rest of the system can function satisfactorily.

The standard for 10KV busbars is
IEC 61439 is a standard developed by the International Electrotechnical Commission (IEC) that covers design verification for low-voltage electrical products and assemblies. The IEC standard for busbar sizing provides detailed guidelines to help engineers select appropriate busbar dimensions. The table, in addition to giving specifications regarding the maximum thickness of the busbar, the maximum current and the maximum nominal voltage, distinguishes between busbars mounted in a "Face to Face" or "Edge to Edge" arrangement. The association has a strong track record in the development and implementation of standards to promote safety and product performance for the benefit of manufacturers and their customers. The design of busbars in Medium Voltage (MV) switchgear must strictly adhere to a series of industry standards.

Standard Colors for Electrical Distribution Box Protection
If a circuit includes a neutral or midpoint conductor, then it should be identified by a blue colour (preferably light blue ). Light blue is the colour used to identify intrinsically safe conductors, and must not be used for any other type of conductor. The preferred colours for AC phase conductors are: • L1: Brown The mandatory colors for power wiring in the National Electrical Code (NEC) are Green, Bare, or Green/Yellow (a yellow stripe or band on green) for the protective ground (PG), and White (or alternatively Gray) for the neutral wire. The international standard IEC 60446 Basic and safety principles for man-machine interface, marking and identification - Identification of equipment terminals, conductor terminations and conductors was a standard published by the International Electrotechnical Commission (IEC) that defined basic. Many countries, including the UK (BS-7671), China, Russia, Hong Kong, Singapore, Ukraine, Belarus, Kazakhstan, Turkey, Israel, South Africa, Argentina, Malaysia, Saudi Arabia (KSA), and the UAE, have adopted the IEC wiring color codes.

Bus copper busbars in high-voltage switchgear
In , a busbar (also bus bar) is a metallic strip or bar, typically housed inside,, and for local high current power distribution, transmission, or switching substations. Busbar design in switchgear ensures safe, reliable power distribution by balancing current capacity, thermal performance, mechanical strength, insulation, and standards compliance. Busbars are constructed from conductive metal bars, typically made of copper or aluminum, with a large cross-sectional area and insulated by specialized materials. These metal bars are connected together using welds or bolts, forming a complete conductive system. In most assemblies you will find horizontal main bars, vertical risers, neutral and equipment-ground buses, and purpose-designed.
