Harmonics in Power Systems
What are harmonics? Harmonics are frequency components in an electrical signal that are integral multiples of a fundamental frequency. Harmonic components distort the electrical signal as they are superimposed on the fundamental frequency component. These harmonic currents arise from non-linear loads in the distribution system, including rectifiers, discharge lighting, and magnetically saturated devices. A load […]
Guardians of Power: The Key Functions of Protection Relays in Complex Systems
At Divergent Engineering our highly experienced team are experts at programming protection relays to achieve protection coordination as well as commissioning and testing protection relays. This blog post will explore the key functions and integration of protection relays in complex systems. What is a protection relay? A protection relay is an electrical device designed to […]
HV submission of new Run-of-Mine (ROM) overland conveyors
Divergent Engineering recently had a high-profile client finalising its mine operation expansion with the addition of a new ROM. The client is scheduled to construct the project onsite within this year, which will require the installation of two new substations – each includes 33kV switchgear, a 33/6.9 kV transformer, 6.6kV MCC, 6.6kV VSDs, 33/0.415kV transformer […]
Arc Flash Hazard Analysis for HV Switchgear with Bus Zone Protection
Although rare, the bus zone fault can occur in several scenarios, such as circuit breakers or insulation support failure. Most HV switchboards have bus zone differential protection to avoid arc flash caused by these failures. Besides the bus itself, bus zone protections cover other components of the switchboards, such as circuit breakers, disconnecting switches, instrument […]
