Fuses are burned at time of over current flows in the ckt but breaker are just open at the time of over current flows.

Answer / lakshmanan.p

Both are protective devices.Fuses are cannot reuse,but the breaker can reuse.breaker can use for any voltage but fuses used only in the limited voltage only.

Answer / chreamz

A fuse is a normally closed protective device that ionises
(burnout open circuitry) under fault condition or when
current over its rating flow through it. Everything happens
automatically with no external actuator. Once blown, it
must be replaced. A circuit breaker if also a protective
device that gets a closing/tripping command from the relay.
It has internal & external devices (actuator) that bring
about execute the action sent by the relay. The life span
of the CB depends on the load, operation and maintenance.

As we know that during saturation test of CT from secondary side, the current in secondary shoots up after core saturation. How core saturation effects the secondary current?

we all know that in transformer, voltage and current are inversely related i.e. Vp/Vs= Is/Ip....so in standard CT..we have a ratio of 200/5...that means our voltage should increase by ratio of 40..althoug that is not the case...because that requires high insulation level.and pratically not feasible......can anybody clarify my ques.......thanx
