RATED voltage is the voltage on the nameplate – the “design point” for maximum power throughput and safe thermal operation. OPERATING voltage is the actual voltage applied at the terminals to the electrical equipment. For example – a machine has a rated voltage of 4160 volts at 60 Hz.
What is the meaning of rated voltage?
The rated voltage is the value of voltage used to designate the switchgear and to which is related its operating performance. The rated voltage indicates the upper limit of the highest voltage of systems for which the switchgear is intended.
What is rated voltage of DC motor?
Typical DC motors may operate on as few as 1.5 Volts or up to 100 Volts or more. Roboticists often use motors that operate on 6, 12, or 24 volts because most robots are battery powered, and batteries are typically available with these values. Operating Current.
What is the difference between nominal and rated voltage?
Explanation: The ‘rated voltage’ is the maximum voltage that the circuit-breaker can interrupt safely and without being damaged by excessive arcing. The ‘nominal voltage’ is the voltage for which the circuit-breaker is intended to be used.
What is Volatge rating?
The voltage rating of a cable is the highest voltage that may be continuously applied to a completed cable construction in compliance with the relevant cable standard or specification (refer to this link if you’re not sure what the definition of a volt is). It’s the voltage a cable can remain stable in operation up to.
How do you read a rated voltage?
The rated voltage of a cable is normally expressed by the combination of two values Uo/U, expressed in volts: Uo being the Root Mean Squared (r.m.s) value between any insulated conductor and ‘earth’ (the metal covering on the cable or the surrounding medium);
How is rated voltage calculated?
Use the formula: P(KVA) = (V^2/R)/1000 where R is resistance in ohms. For example, if V is 120 volts and R is 50 ohms, P(KVA) = V^2/R/1000 = (14400/50)/1000 = 288/1000 = 0.288 KVA. Calculate power rating in KVA when you know power in watts and the power factor.
What is nominal voltage of motor?
These terms are defined as follows: Nominal Voltage: The manufacturer-recommended voltage at which to operate the motor. Most DC motors come with a recommended range of voltages, but the nominal voltage is the voltage that the motor was built to operate at.
How are DC motor rated?
DC Motors are typically rated in terms of : Rated voltage: The operating voltage on the input side of the motor. Rated power: Power (in horsepower – hp or watts) that the motor is designed to deliver to the load (i.e., output power) for continuous operation.
What is the rated condition of a motor?
When you say “rated” it means the highest value that the corresponding equipment can withstand . Suppose a motor is rated at 230 V a.c. then it means that motor need 230 V a.c. neither higher nor less for its accurate and precise operation.
What is the rated output voltage?
Rated output voltage means the allowable peak potential, in volts, at the output terminals of the x-ray high-voltage generator. … Rated output voltage shall be AC 220V±10% over the full range of normal battery operating voltages.
What is rated maximum voltage?
Rated voltage is the max. AC or DC voltage that can be continuously applied at the rated ambient temperature or terminal temperature.
What is rated operational voltage?
Rated operational voltage (Ue)
This is the voltage at which the circuit-breaker has been designed to operate, in normal (undisturbed) conditions. Other values of voltage are also assigned to the circuit-breaker, corresponding to disturbed conditions as noted in Other characteristics of a circuit-breaker .
Why is voltage rated?
A voltage rating is an evaluation based on research and experimentation that help determine how much voltage can be safely utilized by a particular device or form of wiring over the life of the device or wiring.
What does 500V mean?
What does the data 300V/500V or 600V/1000V mean? These specifications describe the permissible nominal voltage of a cable, specified in volts. The first value is the maximum permissible effective value between conductor and protective conductor.
What is transformer voltage rating?
Transformer ratings are measured in volt-amperes (VA) or kilovolt-amperes (WA). Transformer Ratings. Engineers rate power transformers according to the maximum output voltage and current they deliver.
