High Voltage Switchgear

High Voltage Switchgear The power system deals with voltage above 36KV, is referred as high voltage. As the voltage level is high the arcing produced during switching operation is also very high. So, special care to be taken during designing of high voltage switchgear. High voltage circuit breaker, is the main component of HV switchgear,…

Generate three phase power by 3 single phase generators?

Many installation sites need electric power for construction activities. When the site not large all construction equipments are powered with single phase supply. Such single phase DG sets may be available. Site gets single phase supply from utilities for construction. A new construction equipment requires a three phase supply. We have three DG sets of…

Why we use 3 phase power supply, not 4/5/6 phase

Single-phase motors have unambiguous rotation (with a capacitor start), and with a center tap neutral, a single-phase system can be balanced. I’m not sure regarding the economics of multi-phase systems. It seems to me that for each phase added, the total power capacity is increased by one line-ground voltage times one line current so there…

Difference between 50Hz and 60Hz frequency

50Hz vs 60Hz in operating speed The primary difference between 50 Hz (Hertz) and 60 Hz (Hertz) is, well, 60Hz is 20% higher in frequency. For a generator or induction motor pump (in simple terms) it means 1500/3000 RPM or 1800/3600 RPM (for 60Hz). Lower the frequency will be the iron losses and eddy current…

How to convert 60Hz to 50Hz frequency

What is 50Hz, 60Hz? Alternating current (AC) is changing the direction of the current periodically; Cycle is the time of a cyclical change of the current; Frequency is the times of the current changes per second, unit Hertz (Hz). AC current direction changes 50 or 60 cycles per second, in accordance with 100 or 120…
