The temperature is 7 oC.
If it is a portable generator the breaker should be self contained within the generators panel. If the generator is a stationary standby unit a voltage has to be stated to calculate the conductor size and hence the breaker size to protect the conductor. Amps = Watts/Volts.
The generator circuit breaker or gcb is a circuit breaker which is connected with the generator . Whenever there is a fault in the generator the circuit breaker trips and disconnects the generator from operation thus it helps the place from a serious accident etc..
The cable that is used to connect from the generator is based on the size in kW's of the generator and the generator's breaker size rated in amps. It usually is a flexible cab-tire 4 wire cable if the generator is a portable type. If it is a stationary generator is has to be wired with a flexible conduit so as not to transmit vibration from the generator to the conduit system.
Lavoisier proposed a new theory of combustion that excluded phlogiston in 1777. He found that most acids contained breathable air. Lavoisier called it oxygène, from the two Greek words for acid generator.
A generator converts mechanical energy into electrical energy.
In case of vapour compression cycle (VCC) the COP is given by (desired effect / work input). in the other words it can be defines as what we want and what we are paying for that... so in VCC the paying amount is very less as due to low temperature difference that why its value is more than 1. but in case of vapour absorption system the COP is given by (heat taken by evaporator/ heat given to generator). the heat input taken by evaporator is less as compared to heat given to generator.. that why its COP is less than 1......
The generator in a vapor absorption system for a refrigerator consists of all of the components that make the refrigerator work. The system allows for compression, condensation, evaporation, and expansion.
A self-contained motor/generator that can make electricity available whenever it is used.
The operating temperature for a 1500 kVA diesel generator can vary depending on the specific model and manufacturer. It is important to check the manufacturer's specifications for the specific generator model to confirm its exact operating temperature range.
considering a single airconditioning unit, suggested size of generator is 110% of combined electric power required or in the nameplate of compressor + fan motor + evaporator (Fan Coil Unit) if split unit type.
The permanent magnet generator is a synchronous machine where the rotor windings has been replaced with permanent magnets. This eliminates the excitation loses in the rotor, which otherwise typically represent 20-30% of the total generator loses. The reduced losses also give a lower temperature rise in the generator, which means that a smaller and simpler cooling system can be used. The temperature reduction in the rotor also reduces the temperature in the bearings, improving reliability by increasing the lifetime of the bearing and bearing grease.
If it is a portable generator the breaker should be self contained within the generators panel. If the generator is a stationary standby unit a voltage has to be stated to calculate the conductor size and hence the breaker size to protect the conductor. Amps = Watts/Volts.
False
The rear of the generator, right on the manifold

SYNCHRONOUS GENERATOR CAPABILITY LIMITTsynchronous generator capability limiters are as follows 1.MVA or armature current limit of generator: this depends on the cooling system of generator so that temperature rise in generator is limited to safe value.depending on cooling system effectiveness and temperature limit for the insulation used in generator, MVA limit is decided.2.MW limit: this is determined by the power output capacity of prime mover to which generator is connected.3.rotor angle limit: this is related to stability of generator which is synchronised to the grid.ideally this could be 90 degree, but in practice this is limited to70 degree so as to have better stability margin in transient and dynamic condition.the generator falls out of synchronism in trasient condition if rotor angle is close to 90 degree.4. rotor current limit: the field winding placed on rotor has got limited current carrying capacity, beyond which it may burn .so this limit is used.all these limitters make capability curve of g generator within which the generators operates safelyr. k.niranjanemail id: rkniranjan@yahoo.com
Both temperatures are related to the saturation temperature in the steam drum of a heat recovery steam generator. The approach temperature is the water temperature at the economizer outlet, which in many analyses is assumed to be equal to the saturation temperature for simplicity. The "pinch point temperature difference" is the difference between the saturation temperature and the gas temperature at the economizer inlet.
