A method is proposed for calculating the incident energy and the arc flash boundary distance for dc systems when an arc is bounded inside a space such as a battery cabinet. The so-called “arc-in-a-box” has a focusing effect in which radiated energy strikes the back and sides of the box, reflecting out in a higher concentration of.
The article is an overview and can help in choosing a mathematical model of energy storage system to solve the necessary tasks in the mathematical modeling of storage systems in electric power systems. Information is presented on large hydrogen energy storage units for use in the power system.
To generate the HV pulses the main capacitor bank is charged to a voltage at the 10 kV level. Via the semiconductor switch the pulse transformer is connected to the capacitor bank. With the step up ratio of 1:12 the voltage is transformed to the 120 kV level. During the pulse the voltage of the main capacitor droops for about 19 %. The .
Minimum resistance is calculated as follows: Rm = kV + 1. where: (Rm is minimum resistance to ground in Meg--Ohms and kV is rated nameplate voltage defined as Kilovolts.) Example: For a 480VAC rated motor Rm =1.48 meg--ohms (use 5 M ). For a 4160VAC rated motor Rm = 5.16 meg--ohms.
