Do you know that on average, Vietnam has 250 casualties per year due to electrical accidents and this number tends to increase year by year. Actually, electricity is an indispensable part in our daily life so electrical accidents are absolutely inevitable. Having many years experience in electrical field, MEC International believes that the electrical engineering systems providing electrical safety and power quality play a fundamental role in building construction. Therefore, to avoid unfortunate accidents caused by electricity, MEC recommends some tips for Electrical Engineering System.

Firstly, MEC always uses electrical protection devices. The main function of electrical protections is to disconnect the power supply when dangerous operating conditions are present. When voltage changes suddenly, the fault is called voltage surge. Voltage surges normally occur when large equipment is switched, and can also be caused by lightning. Since circuit breakers are not designed to protect installations from voltage surges, you must use a surge protection devices (SPD) or transient voltage surge suppressor (TVSS).

Secondly, our engineers conclude that improving power quality in electrical Engineering Systems is very necessary. Without the proper power, electrical devices may damage, fail prematurely or not operate at all. There are many causes of poor quality power, these are not faults strictly speaking, which are however also detrimental for performance. Two of the main issues are low power factor and harmonics.

Finally, The best recommendation from MEC to keep all these electrical issues under control is to seek professional assistance from an electrical engineering profession. In new constructions, protection and power quality can be solved by suitable design. For completed buildings, for protection and high power quality, power factor monitoring equipments are be used to detect harmonics and low power factor, the measurement results are then used to control harmonic filters and capacitors.

These above tips from MEC are very effective and we always apply for every project we participate in. Beside installing, MEC also takes responsibility for maintenancing electrical system for buildings. Since MEC always tends toward to long term targets and make our clients satisfied with our services even after projects totally completed.
