50 Hertz Industrial Electricity
All of Europe and most of mainland Asia and Africa use 50Hz frequency for their industrial electrical needs. Industrial motors operate better at this frequency, since the voltage drops could be easily maintained.

How many amps can be applied to a 400 sq mm aluminium wire?
Asked by Wiki User
530 amps in average conditions, more in cold weather.
<<>>
The closest conversion will be; 405 mm2 is equal to 800 MCM AWG.
A 800 MCM aluminium conductor with an insulation factor of 90 degrees C is rated at 445 amps.
Can you wire a 240 volt oven to a 13 amp plug?
Asked by Wiki User
From your question, and the terminology used, you appear to be referring to the UK residential electrical system. The following answer therefore refers only to a UK installation.
Most ovens ('cookers') are designed to operate on a separate circuit with its own circuit breaker or fuse (e.g. 30 A for ovens up to 12 kW, or 45 A for ovens above 12 kW). Trying to operate such a oven from a 13-A circuit will simply cause the plug's fuse to operate, disconnecting the oven from the supply. So, while the oven will be protected, you won't be able to use it as it will keep blowing the fuse in the plug! It certainly won't melt the plug, as suggested in the original answer.
However, some small, countertop, ovens (e.g. the 'Baby Belling' brand), which are specifically designed for use in the kitchens of small flats or apartments ('bed sitters') are specifically designed to run off a 13-A plug.
What does it mean by meggering?
Asked by Wiki User
On the whole megger testing is non destructive. What happens is a DC voltage is applied to the device or winding under test. It is an insulation test to see is the insulation has been injured in any way to cause a short circuit when normal power is applied to it. On my megger there are 3 ranges 300V, 750V, and 1000 volts. Applying the proper voltage is essential to not damaging the device you are testing. Working voltages up to 240 volts should use the 300 range. Working voltages up to 600 volts use the 750 volt range and working voltages above 600 use the 1000 volt range. As you can see if you used the 1000 volt range on a device that had a working voltage of say 24 volts you could damage the insulation just by testing it. So meggering a device is non destructive if you use the tester as its instructions tell you to.
What is captive generation in power sector?
Asked by Wiki User
Industries have their own DG sets to generate power in case state power is not available. This power generators are known as captive generation
Can you collect one 220 volt phase from a 380 volt three phase plug?
Asked by Wiki User
Answer for UK and countries running a 50 Hz supply service.
The voltage potential of 380 volts is not common to North America.
It will probably be difficult to tap into the plug to get the voltage.
If you have a three phase 380 volt supply from a source then you can obtain a single phase voltage of 220 volts from it. 220/380 is a wye voltage connection. 380 divided by 1.73 will give you 220 volts. L1 - N = 220V, L2 - N =220V, L3 - N = 220V. L1 - L2 = 380, L2 - L3=380, L3 - L1 = 380.
What type of connection is used in power grid connection between generation and distribution?
Asked by Wiki User
A step up transformer is used at this junction in the electrical transmission system.
What happen when you remove braking resistor on the inverter?
Asked by Wiki User
The system will lose it's regenerative braking function, if there is no other means to stop the motor it will coast to a stop.
How do you connect the 3 pin plug?
Asked by Wiki User
One pin for phase other pin for neutral and third one is for earth/ground wire.
In India the right pin is for phase, left pin is for neutral and pin on top side is for ground wire. This third top side pin is slightly bigger and longer compared to phase and neutral pins.
What will happen if a 250 VDC coil is used to replace a 440 VDC coil?
Asked by Wiki User
The coil will burn out due to having almost double the voltage being applied to it.
What is difference between 5 amp and 15 amp plug points?
Asked by Wiki User
Current carrying capacity is different.
What is the use of SCM ct in generator?
Asked by Wiki User
SCM CT is a normal CT which is connected in two phase of the turbines & its terminals are connected to the AVR. Depending on the load on the turbine the current increases & accordingly it gives the input to the AVR so as to develop the required field to generate the same load without any dip in the voltage.
Can you put a 15 amp fuse in an electric fire plug?
Asked by TraceyEvans
I would say no as it could blow and if majorly can damage the plug and can be expensive to repair
How many kilowatts equals to one ampere?
Asked by Wiki User
To answer this question a voltage and pf (power factor) must be stated. kW = I x E x pf/1000.
Does a dimmer light have a device in it?
Asked by Wiki User
Yes, there is a device inside it to allow the unit to dim the lamp.
Why need to discharge an electric power when carry out any repair?
Asked by Wiki User
Discharging is done for the sake of safety to personnel. If there are any capacitors in the circuit that you are working on and you physically ground one out through yourself you can receive a very nasty shock. Most capacitors today have bleed resisters across the working terminals which usually take about a minute to discharge the device.
Why is a heat-sink used on some equipment?
Asked by Wiki User
The main purpose of a heat sink is to dissipate excessive heat away from the device that it is attached to. Some small integrated circuit components are so physically small that an over excess of heat generated by themselves would destroy the device. The heat sink is placed on the IC to prevent this from happening.
