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 is considerede low voltage?
Low voltage is a relative term, as there is no 'level' at which a voltage is rated 'low'. Electrical safety codes define low voltage as circuits that do not require the same protections necessary at higher voltages.
How do you calculate voltage regulation of 33kv and 11kv distributions?
Regulation =(Obtained voltage per phase - rated voltage per phase)/rated voltage per phase *100
What is meant by rated voltage rated current and rated power of a transformer?
The ratings state the limits on voltage and current for operating the transformer at full load. The rated voltage times the rated current gives the rated VA of the transformer. Transormers are not usually rated directly for power because this depends on the power factor of the load applied.
What is meaning of apparent power in transformer?
Apparent power is the product of voltage and current in an a.c. system, and is expressed in volt amperes. The rated apparent power of a transformer is the product of its rated secondary current and rated secondary voltage.
What is the meaning of rated lightning impulse withstand voltage?
That is the voltage rating the product can stand up to. If the lightning withstand voltage was 100,000,000V, that means the item could get struck by lightning that is up to 100,000,000V without damaging it.
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 is rated voltage and current in transformers and how to calculate them if given 50k VA?
Rated voltage is the voltage at primary side. Rated current can be found from the equation, Rated Current= Output KVA / Output rated voltage

What is considerede low voltage?
Low voltage is a relative term, as there is no 'level' at which a voltage is rated 'low'. Electrical safety codes define low voltage as circuits that do not require the same protections necessary at higher voltages.

What are the ratings and certificates for Irresistible Impulse - 1996 V?
Irresistible Impulse - 1996 V is rated/received certificates of: USA:R
What voltage is the kettle?
It depends where you bought it. In North America, its rated voltage will be 120 V whereas, in Europe, its rated voltage will be 230 V.
What is meant by rated voltage?
the voltage which is mainly applied to primary side of the transformer is called rated voltage.Answer'Rated voltage' is the nominal voltage at which an electrical device has been designed to operate.
How do you calculate voltage regulation of 33kv and 11kv distributions?
Regulation =(Obtained voltage per phase - rated voltage per phase)/rated voltage per phase *100
What is withstand voltage?
It is the rated test voltage that will not cause insulation breakdown.
What are the ratings and certificates for Enterprise - 2001 Impulse 3-5?
Enterprise - 2001 Impulse 3-5 is rated/received certificates of: Australia:PG
