The starting current of a chiller machine can typically range from 5 to 10 times its full load current (FLC), depending on the type of compressor used. For example, if the FLC is 100 amps, the starting current may reach between 500 to 1000 amps. The ideal ratings for a Molded Case Circuit Breaker (MCCB) should accommodate this starting current, often selecting an MCCB rated for around 125-150% of the starting current to ensure proper protection and avoid nuisance tripping. It's also essential to consider the chiller's specific manufacturer guidelines and local electrical codes when selecting the MCCB.
There are 3 cases in C.B. paralleling: 1. Both Circuit breakers of same current ratings with same time settings. 2. Both circuit breakers of different current ratings 3. Both Circuit breakers of same current ratings with different time settings. Case1: Any of the C.B.trips (depending on CT characteristics as no two CTs' can have same characteristics) Case 2. The one with lower current ratings would trip first. Case 3: The one with lower time settings would trip earlier.
Is used to reduce the short cct current levels within the ratings of the equipment on the load side of the reactor
VA Rating stands for Volt-Ampere Rating, It is the basic unit of Alternator or Transformer. This is so because in AC System Power(P) is the product of Voltage(V),Current(I)and Power Factor. Power(P) = Voltage(V) * Current(C) * Power Factor But power factor of the load is never constant and depends on the type of load. So to resolve this problem power ratings of the above mentioned machine is always rated in VA or KVA and its the product of voltage and current.
The size of a drilling machine is typically specified by its drill bit diameter and the maximum depth it can reach. Additionally, specifications may include power ratings, such as horsepower or wattage, and the machine's weight or dimensions, which indicate its portability and suitability for various applications. These factors help determine the machine's capacity and effectiveness for specific drilling tasks.
It depends of your panel ratings. usualy, a panel short-circuited has a maximum current, you can base the value on that. But if you are doing an array of panels, you have to pai attention to the parallel connection, once that multiplies the current across the circuit. in this case you have to use diodes that support the current of the array.

There is no such thing as a 'total current' for a three-phase generator in the sense that you suggest -i.e. the sum of the phase currents. Current ratings are based the current that the machine can deliver to a load on a 'per line' basis.

Well, isn't that a happy little question! To find the starting current for a 110 kW motor, you can use the formula: Starting Current = (Motor Power / (sqrt(3) x Voltage x Power Factor x Efficiency)). Remember, it's all about happy little calculations and making sure your motor has a smooth and joyful start.
