Safety precaution for Electrical works

Every step we need to consider about hazards when perform electrical works. Only competent electrician can work on electrical installation or live condition according to relevant industrial safety standards. Common industrial safety standard for electrical works such as VDE 0105 for Germany, and international standards for EN 50110 or IEC 60364. For electrician, they need…

Difference between 50Hz and 60Hz frequency

50Hz vs 60Hz in operational speed The primary distinction between fifty rate (Hertz) and sixty rate (Hertz) is, well, 60Hz is two hundredth higher in frequency. For a generator or induction motor pump (in straightforward terms) it means that 1500/3000 revolutions per minute or 1800/3600 revolutions per minute (for 60Hz). Lower the frequency are going…

Neutral-Grounding-Resistor System

Neutral-Grounding-Resistor System Neutral-Grounding Resistors (NGRs) are used to ground power systems by inserting a resistor between the system neutral and ground. This lowers the prospective ground-fault current to a predetermined value. A properly designed resistance-grounded system provides benefits over both ungrounded and solidly grounded systems. Because the system is grounded, transient over voltages do not…

What is GFCI and what is the use in electrical field?

Ground Fault Circuit Interrupter (GFCI) At home or outside, there is no way can we do without electricity and electrical devices. These are the indispensable necessities of our modern day lives. But sometimes their accidental “touch” can give a painful shock resulting in serious injuries which at times, sadly enough can have fatal consequences. Incidents…
