rated power must be determined. Engines or generator sets may have more than one rating, e.g. continuous power, prime power, and emergency stand-by power. The highest power rating applied in the application should be used. The rated power output of an engine in kilowatts (kW) or sometimes horse power (hp) is often.
Send message »· Power resistors are used as grounding resistors to limit fault currents, high voltages and act as protective relays. These resistors can be rated up to 8 Kilo Amps. Power resistors are used as load resistors in turbines and Uninterruptible Power Supplies.
Send message »Parameters. Rated voltage (V p): The rated voltage of the generator in volt (V).; Phase: Specify the phase arrangement. 1 Phase AC or 3 phase AC. Generator rating (S): Specify the the generator rating in kW or kVA. When the rating is in kW, you also need to specify the power factor cos(Φ), which is a number between 0 and 1.
Send message »Neither. You're confusing energy and power. Power is energy per unit of time, and one watt is one joule per second. So if you have a 10 W device, that means, that it's consuming 10 J each second. Now, the issue with electric energy is, that joule, as a unit, is quite small. Therefore, we use larger units, such as wat·hour or kilowatt·hour.
Send message »Rated vs. Nominal Current Joel Goergen, 1/22/18 "Rated current" is defined by the following: Generally, rated means that the product is marked on the nameplate with the rating. E.g. 100-120Vac, 1A, 50/60Hz. Then, in most standards, there is an input current/power test where you verify that you do not exceed the rating by more than 10%.

Send message »An electric motor's nameplate or rated power is its output power, not its electric input power. Electric power consumption is rated power divided by motor efficiency. Rated power depends on class of motor (which considers intended duty). Industrial grade motors usually are rated for continuous duty.
Send message »This represents the number of AC power lines supplying the motor. You either have a single-phase or 3-phase motor. #6: FULL LOAD RPM Full load RPM (Revolutions per Minute) of the motor is approximate speed under full-load conditions, when voltage and frequency are at the rated values. It is generally given as "RPM" on the nameplate.

Send message »First, you must understand that these terms are not always used in exactly the same way and that there are other ways of saying the same thing. The "rated power" is the amount of power that something was designed for. For example, the rated power.
Send message »For example, a 3 MW mission critical standby-rated generator set will provide power for the duration of an outage. It could be run for up to 500 hours per year and have an average load factor of up to 2.55 MW. Prime. In this application, the generator set is capable of providing power to a varying load for an unlimited number of hours per year.

Send message »· While this is not a linear scale, lets say at 50% of the rated load the UPS will run for 20 minutes and at of the rated load the UPS will run for 10 minutes. The load they are referring to is the amount of watts your devices use vs the power rating of the UPS.
Send message »In practice, this power supply would probably reach its limit at a load of 350W on the 12V rail. Ironically, even a good 425W PSU could push more power than this model at 12V. Don't fall for.

Send message »Hence, Rated voltage is the maximum voltage limit at which the device can be operated safely. Rated voltage is mostly defined with the tolerance rate, where tolerance is given in percentage. The tolerance shows the minimum and maximum range. For example, if the rated voltage of the device given is 100v with a tolerance of 10%.

Send message »At half its rated operating speed, the fan delivers 50% of its rated airflow but requires only 1/8 full-load power. Even with a reduced motor efficiency of 77.8% and drive efficiency of 86%, with adjust-able speed operation the power required by the fan and the VFD is only 2.8 kW. For this example, input power requirements are reduced by 82.9%.

Send message »Power supply efficiency is the amount of the actual power delivered to the components divided by the electrical power drawn from the mains supply socket. If a power supply with 50% efficiency is required to provide a 50W power to a load, it will draw 100 W from the wall. The other 50% gets wasted as heat and other losses.
