Electrical Engineering Consultants

Electrical energy is extremely efficient to store and easy to transfer and as a result is most commonly used throughout the world for the operation of devices and equipment. In addition to operating mechanical systems, electricity is also used as an energy source for chemical processes (e.g. refining), thermal processes (e.g. smelting) and electronic systems.

The field of Electrical Engineering covers the design, installation, operation and management of electrical distribution and electrical storage systems. It relates to the safe, efficient and reliable transfer (i.e. supply) of electrical energy to power equipment and systems that are used within an operating plant or site. Electrical Engineering is also designing the transmission and distribution of power for systems such as instrumentation and control systems, electrical plant and equipment as well as communications networks.

Orana Engineering is experienced with the Electrical Engineering of both LV (Low Voltage) and HV (High Voltage) systems and has the capabilities and resources to provide engineering services for:
