Circuit Breaker Time Interval Meter

About Circuit Breaker Time Interval Meter

In today's most developing electrical world, technologies such creatively modifies and rapidly growing the

development of high voltage switching devices and there we came where high voltage breakers born. In such modern

period of electrical world High-Voltage Switching is not a huge complex thing such as in past two decades.

The High-Voltage switches called Breakers are such designed to moderates all the risks of switching the extra high

voltages. And as we are victims of such modern period, hence we had to accept that these kinds of HV circuit Breakers

are being rapidly used by us.

In high voltage yard, all equipments should be such designed to overcome the harmful acts assumed by future aging

effects. Also they should be periodically tested its all parameters by various testing instruments. One of the most

common tests performed in HV Circuit Breaker is Timing Test. The breaker should maintain its close time as well trip

time, as when fault occurs it should be actuated such fast that the fault level should have the minimized of its own

harmful effects.

At the vice versa of the fast tripping time setting, at the time of closing the breaker it will produce the more number

of bounces which is also not good for contact area of poles, as it creates spark due switching of high voltage and hence

the surface contact resistance of poles decayed. So overall the inertia of spring for poles should be such adjusted to

comfortably operate the breaker in both Trip as well Close command.
