Lightning: All of a sudden people recently benefit from the marked developing service of bank and finance as through it was integrated with network of thing. At the same time , lots of electronic devices and computers must escape the influence of ambient factors such as ground potential attack when lightning occurs .Network bank , mobile bank ,and ATM etc data analyse center are be sure of electrical safety.
Faulty Arc : As up-mentioned , mass of wiring paths and electronic devices gathering to elevate the load in circuit . common causes of arc faults include faulty connection and ground potential attack .
Arc fault caused by them discharge translates into heat , which can break down the wire’s insulation and damage equipment important , even possibly trigger an electrical fire. Most of mistakes of circuit in bank will influence the flow of working and service due to incalculable economic loss and people loss .
Harmonic and three phase unbalance : Electrical safety for bank is every important , in order to improve the reliability of bank power supply and information safety , there are three modes of power supply, which of them can be automatically switched , it composed of general electricity , self- equip generator and UPS. Gathering use of power electronic components based on the switching power supply equipment and arrays with strong nonlinear equipment as UPS equipment , computers , servers , converter, air conditioners and energy save lighting , leading to serious pollution of harmonic and three phase unbalance .
1 Increasing of consumption of equipment and arc fault , leading to aging circuit and heat.
2 Harmonic pollute the circuit of equipment , resulting in low voltage distribution equipment malfunction.
3 Lost of data and the delay of information caused by harmonic .
4 Malfunction or faulty work of ATM make bank and deposit in trouble and loss.
