- Q2. What is the maximum range of voltage rating for belted cables are in used?
- Ans.
The maximum range of voltage rating for belted cables varies depending on the specific application and industry standards.
The voltage rating of belted cables can range from low voltage (LV) to high voltage (HV).
LV belted cables typically have a voltage rating of up to 1 kV.
HV belted cables can have voltage ratings ranging from 1 kV to several hundred kilovolts (kV).
The exact voltage rating of belted cables is determine...
- Q3. The distribution systems are mostly used in India
- Q4. Conventional flow assumes charges flow from
- Ans.
Conventional flow assumes charges flow from positive to negative terminals.
Conventional flow is based on the assumption that current flows from positive to negative terminals.
This convention is used in electrical engineering and circuit analysis.
For example, in a battery-powered circuit, conventional flow assumes that electrons flow from the positive terminal of the battery to the negative terminal.
- Q5. How much torque a synchronous motor can develop?
- Ans.
The torque a synchronous motor can develop depends on its size and design.
The torque is directly proportional to the current supplied to the motor.
The torque also depends on the strength of the magnetic field produced by the rotor.
Larger synchronous motors can develop higher torque than smaller ones.
For example, a 500 kW synchronous motor can develop a torque of around 1500 Nm.
The torque can also be affected by factors
- Q6. An underground system cannot be operated above
- Q7. What can protect a cable against mechanical enjury?
- Ans.
Cable protectors can safeguard cables against mechanical injury.
Cable protectors can be used to cover and shield cables from physical damage.
Flexible conduits or cable trays can be installed to provide a protective pathway for cables.
Using cable ties or clamps to secure cables in place can prevent them from being accidentally pulled or strained.
Applying cable armor or armored cables can provide additional protection ag...
- Q8. Earth wire or ground wire is made of
- Ans.
The earth wire or ground wire is typically made of copper or aluminum.
The earth wire is an essential safety component in electrical systems.
It is used to provide a path for electrical current to safely discharge into the ground.
Copper is commonly used for earth wires due to its excellent conductivity and corrosion resistance.
Aluminum is also used in some cases, especially for overhead power lines.
The earth wire is usua...
- Q9. Average resistance of a human body is
- Ans.
The average resistance of a human body is approximately 1,000 ohms.
The resistance of a human body can vary depending on factors such as skin moisture, contact area, and voltage applied.
Dry skin has higher resistance compared to moist skin.
The resistance can be affected by the presence of sweat, water, or other conductive substances on the skin.
The resistance decreases when the contact area between the body and a conduc...

Thermocouples are used to measure temperature inside the furnace.
Pyrometers are used for non-contact temperature measurement.
Pressure gauges monitor the pressure levels within the furnace.
Flow meters are used to measure the flow rate of gases or liquids in the furnace.
- Q2. How to calculate the mills roller thrust in your plant.
- Ans.
Calculate mills roller thrust by considering the load on the rollers and the angle of contact.
Calculate the load on the rollers by considering the weight of the material being processed and any additional forces acting on the rollers.
Determine the angle of contact between the rollers and the material being processed.
Use the formula: Roller Thrust = Load on Rollers * tan(Angle of Contact).
Ensure to consider all relevant...
