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 do you prevent a condensation in LV electrical Panel?

User Avatar

Asked by Wiki User

To prevent condensation in an LV electrical panel, you can install a dehumidifier or use a panel heater to maintain a consistent temperature inside the panel that is above the dew point. Proper ventilation to control moisture levels and regular inspection for any signs of moisture buildup can also help prevent condensation. Additionally, ensure that the panel is properly sealed to prevent moisture ingress.

Where is static electricity and how does it move?

User Avatar

Asked by Wiki User

Static electricity occurs when there is an imbalance of electrons on the surface of an object. It can be generated by friction between different materials or by contact and separation. When the excess electrons build up on an object, they can be transferred to another object through contact, causing a spark or discharge.

Can you get 220 vac 50hz from 380 vac 50hz?

User Avatar

Asked by Wiki User

Yes, you can use a transformer to step down the voltage from 380V to 220V while maintaining the frequency of 50Hz. Transformers are commonly used for this purpose in electrical systems.

Why brushes are made up of carbon?

User Avatar

Asked by Wiki User

Carbon brushes are commonly used in electrical systems due to their high conductivity, resistance to heat, and ability to easily adjust to different commutator surfaces. The carbon material offers low friction and wear properties, making it ideal for transferring current in electric motors and generators. Additionally, carbon brushes provide a stable performance over time and have a long service life.

How much current flows through circuit breaker trip coil?

User Avatar

Asked by Wiki User

The current flowing through a circuit breaker trip coil is typically very low, on the order of milliamps. This current is used to activate the trip mechanism, causing the circuit breaker to open and disconnect the circuit in the event of an overcurrent or short circuit. The exact amount of current can vary depending on the specific design and rating of the circuit breaker.

Who invented fluorescent lighting and alternating current?

Asked by Wiki User

Fluorescent lighting was invented by Peter Cooper Hewitt in 1901. Alternating current (AC) was developed and promoted by inventors Nikola Tesla and George Westinghouse in the late 19th century as a more efficient method of transmitting electrical power over long distances.

Electric energy used in homes is measured using a kilowatt hour meter. This is the meter that is found on the outside of your home just below where the utility company makes a connection to your house.

What is the basic function of PLC?

PLC or programmable logic controller is a digital computer used for automation of electromechanical processes, such as control of machinery on factory assembly line, amusement rides, or lighting fixtures.

What is the capacity of a 35mm2 cable?

User Avatar

Asked by Wiki User

Current carrying capacity is different for aluminum from that of copper cable. Under different conditions like, type of insulation, number of conductors, in conduit, underground, in air, single or multilayer, system voltage, the current carrying capacity varies a bit. Hence You must refer a standard chart from a reputed cable company.

Nikola Tesla invented AC, probably a transformer as well but don't quote that.

What is the current carrying capacity of 185 Sq mm?

User Avatar

Asked by Wiki User

As a rough estimate, for medium voltage cables directly buried in earth, I use 2 A / mm^2 for copper conductors, and 1.2 A/mm^2 for aluminum conductors.

However, the installed capacity of a cable is mostly dependent on how much heat can be dissipated to its surroundings, and ultimately the maximum temperature of the insulation material.

For this reason, it is important to know how the cable will be installed, what conductor is used (Al or Cu), the cable insulation (for both thickness and operating temperature limits), soil thermal resistance (if buried), and if there are other heat sources (cables, process pipes, incident solar radiation, etc) are nearby.

There are several cable manufacturers that provide reference current ratings for nominal installations. Check Nexans, Prysmian, or Okonite (US dimensions).

Where is an mpcb used?

User Avatar

Asked by Wiki User

Motor protection circuit breakers(MPCB) are a specialized type of electrical protection device that is designed specifically for electric motors, like their name implies. Electric motors have plenty of applications and are used to drive mechanical devices of all types, so it is very important to protect them adequately with MPCBs.

What is locked rotor current?

User Avatar

Asked by Wiki User

"Locked Rotor Current" also called LRA which stands for Locked Rotor Amps, is commonly found on electric motor nameplates. Locked Rotor essentially means the motor is not turning. The current or amps in this case have to do with the amount of electrical energy required to start the motor. At the instant the motor is switched on, it is not turning, and draws the maximum current. As the motor starts to turn, the current goes down. This required energy is much greater than the Full Load Amps or Running Amps, which is the current drawn when the motor is running at normal speed under full load. The current required to start the motor will depend on the type of motor as well as the specified design voltage required for the motor, typically the higher the voltage, the lower the required amperage or current.

The term also applies to equipment such as Air Conditioners which have an enclosed motor inside the compressor, as well as the condenser fan(s) etc.

Depending on the type of motor, LR current can be anywhere from 3 to 8 times the normal running current, also called RLA, or running load amps.

Does the circuit box have one side for neutral and the other side for ground?

User Avatar

Asked by Wiki User

No, a circuit box is just a metal or plastic box that encloses the wiring and has means for mounting a cover plate. Most circuit boxes are for mounting outlets or switches, but one type (also called the junction box) is only intended as a junction point for wiring for multiple circuits and its cover plate is solid (no openings).

The wires that pass through a circuit box (usually together in a common plastic jacket) will be identified as:

  1. hot - black (220VAC service opposite phase hot - red)
  2. neutral - white
  3. ground - green

How much current will a 120 VAC wall outlet pass through a connected 20 ohm circuit load?

Asked by Wiki User

The equation that you are looking for is I = E/R. Amps = 120/20 = 6 amps. This is one of the basic equations of Ohm's Law.

What is the cable size for motor 15kw 440 volts connection?

User Avatar

Asked by Wiki User

The current draw is about 27 amps. A motor feeder has to be 125% of the motors full load amperage. 27 x 125% = 33 amps. A #8 copper conductor with an insulation factor of 90 degrees C is rated at 40 amps.
