You can reduce induced voltage in control cable by applying the following methods.
1. While laying control cable keep a minimum distance 300mm from the power cable.
2. If possible try to lay control cable on the separate cable tray.
3. Earth the Armour/ screen of the control cable on both side of the cable or at-least at one side.
Some times it is not important to reduce the the induced voltage in control cable, but it's effect on relay or contactor as the contactor or relay does not pick-down even after the removal of the control supply. In that case it is recommended to use two relay/contactor in parallel and use the contacts in series or parallel for control circuit interlocking.

How do you control speed of a motor?
first do you reduce the voltage level or increase the load factor
How do you reduce voltage in a circuit?
You reduce voltage in a DC circuit with a resistor. If the power demands are high, however, you may need a switching voltage regulator.
What are the advantages and disadvantages of instrumentation amplifier?
Advantages:Even a small value of input voltage can be amplified using instrumentation amplifier.Disadvantages:For transmission purpose for long range, noise also gets superimposed along the original wave. Therefore specific cables are used to reduce noise.
How do you reduce a ripple voltage?
You reduce ripple voltage by adding a low-pass filter. In the simplest case, you put a capacitor after the rectifier. The peak voltage will be the rectifier output voltage less the forward bias of the rectifier, while the minimum voltage will depend on current and capacitance. In a more complex case, you could use an LC filter, making the peak voltage smaller. Specifics are dependent on the power and performance requirements.
How do you reduce the Power dissipation?
Answer for mechanical systems:Use oil or grease to reduce friction!Answer for electrical systems:Making the voltage as high as possible is a good way to reduce power loss.ExplanationThe voltage drop along a conductor is proportional to the resistance and to the current carried. (V=IxR) So, for a given quantity of Power (W=VxI), if the voltage is made as high as possible there will be less current flowing and therefore less power loss.
How do you control audio hiss?
One way to reduce hiss is to increase the quality of the cables you are using.
How does the national grid brings electricity to homes?
By overhead cables, supported on masts, at very high voltage, to reduce the effects of resistance in the wires.
How do you control speed of a motor?
first do you reduce the voltage level or increase the load factor
Why are overhead electricity cables never tightly over a pylon?
Overhead electricity cables are not tightly strung over a pylon to account for factors like temperature changes, wind-induced movements, and maintenance needs. Having some slack in the cables helps to reduce stress on the wires and prevent damage or breakage.
Why is the core is laminated alternatively in motor?
Cores are laminated to reduce circulating currents, called 'eddy currents', which are caused by voltages induced into the core. As each lamination is effectively insulated from its neighbours, its cross-sectional area and, thus, its resistance is increased. Additionally, the voltage induced into each lamination is much lower than would be induced into an unlaminated core -so, the combination of lower induced voltages and higher resistances significantly reduce energy losses in the core.
What is emf induced in a motor's coil that tends to reduce the current in the coil of the motor?
BACK emf induced in a motor's coil that tends to reduce the current in the coil of the motor. The answer should be 'back'.
Do HDMI cables made by Monster Cables reduce noise interference?
Yes the Isolated Clean Power Digital Filters built in help reduce interferance
What happens when you reduce current in the cables?
you lose chanels
How do you reduce voltage in a circuit?
You reduce voltage in a DC circuit with a resistor. If the power demands are high, however, you may need a switching voltage regulator.
Can a rheostat be used to control speed on a capacitor run motor?
No. If you attempt to reduce the voltage to a cap start motor by using a rheostat, you can destroy the motor.
What is frustrated induced criminality?
Frustration-induced criminality is when a behavior directed at a specific goal is blocked, arousal increases, and the person experiences a drive to reduce it.
How do resistors reduce voltage in an electrical circuit?
Resistors reduce voltage in an electrical circuit by impeding the flow of electric current, which causes a drop in voltage across the resistor. This drop in voltage is proportional to the amount of resistance in the circuit.
