Rated insulation voltage is the maximum voltage that can be applied to the insulation of an electrical device without causing a breakdown or failure. It is a measure of the insulation's ability to withstand high voltage without impacting its performance or safety. The rated insulation voltage is typically specified by the manufacturer and is an important parameter to consider when designing or selecting electrical equipment.

What is withstand voltage?
It is the rated test voltage that will not cause insulation breakdown.
What is insulation co-ordination in high voltage engineering?
To provide optimal insulation to high voltage equipments.
What is the formula used to determine insulation resistance in a motor?
2 meg ohms, 2,000,000 ohms to ground. 1 meg ohms.
If the voltage in a resistive is double the power will be?
In a resistive load circuit, the power = multiplication of voltage and Current. By increasing the voltage power will not be increased. Power is defined by the load as per its design. If the voltage is higher the load current will reduce. However running a load at double the rated voltage is not good for the device. Insulation may fail.
Does a high rating mean lots of insulation or little insulation?
It depends what you mean by a 'high rating'!If you mean a high 'voltage rating' then, yes, you will require thicker insulation. But if you mean a high 'power rating', then, not necessarily, because the voltage can be low, while the current is high.Remember, the thickness of insulation depends on the voltage, while the type of insulation (how it withstands higher temperatures) depends on the current.

What is Lightning impulse withstand voltage?
The instantaneous voltage rating of a given insulation sytem. In the case of a lightning strike, it is very high voltage but only for a split second. The insulation is designed to handle this rated voltage for a split second without damage to the apparatus. Any longer, and damage would result.

What happens when a transformer is operated at no load with high voltage?
It depends on how much voltage you have applied. If you apply rated voltage nothing happens only core losses will be there on the transformer nothing will happen apart from that. If you go on increase the voltage core losses will increase and transformer will get heated up. After attaining the breakdown voltage of insulation, insulation in the primary and secondary will fail and the coils will get short circuited then the coils will burn.
What is the amp and voltage rating for number 6 gauge wire?
55 <<>> A #6 copper conductor with an insulation factor of 75 or 90 degrees C are both rated for 65 amps.
What is the formula used to determine insulation resistance in a motor?
2 meg ohms, 2,000,000 ohms to ground. 1 meg ohms.
What harms does low electricity cause to electric appliances?
the power consumption of device is constant (provided no any condition is changed) at low voltage the power draw by motor is same at rated voltage bu according to formula the current is rise .
Why the voltage grade of cable is more than rated voltage?
Cables are classified based on insulation class and noted rated voltage.They are classified based on their nominal voltage.This is the maximum voltage which the cable can withstand for a short time period in the event of a fault.Rated voltage is with respect to continuous time duty i.e. Normal operation condition.

Why 5KV voltage is applied to Megger for insulation resistance measurement?
It is a easy voltage to obtain and can check for breakover in the insulation. The voltage is higher then what would be put through most wire and shows any weakness.
