Symmetrical and unsymmetrical electrical faults

Having built up a reputation for delivering an efficient and professional service, our NICEIC,ECA affiliated company is well recognised across Leicestershire and beyond. Every conceivable kind of electrical work is undertaken by our team courtesy of the most talented of electricians. Problems with electrical appliances is something that we’ll all experience at some point, but whatever it is, we can rectify the issue.

Electrical faults are deviations of currents and voltages from nominal conditions. While in normal operating states power systems carry regular currents and volts that contribute to a safer system operation. But when faults happen, they can in high current levels that may damage your devices and equipment. Mainly, there exists two variations of faults in the power system; unsymmetrical and symmetrical.

Symmetrical faults are severe and happen infrequently in power systems. They’re also called balance faults, with L-L-L-G and L-L-L (L for line and G for ground) making up the types. Only about 2 to 5% of problems are this type and if they come about, the system remains balanced while the equipments become damaged.

Unsymmetrical faults are quite common but less severe than their symmetrical counterparts, with L-G, L-L and LL-G being the varieties here. These are also referred to as unbalanced faults due to their presence causing system unbalances. This refers to the fact that impedance values vary for each phase, culminating in an unbalanced current that flows through these phases. These are tougher to observe and are carried by per phase basis, just like three-phase balanced faults.

At Q-Energy, we are fully trained and equipped to handle both large and small electrical complications in the commercial, domestic and industrial sectors. Our customer-base has been built on recommendations and we hope that you can provide positive testimony too once we’ve served you.
