What is spn isolator switch?

An SPN isolator switch is a circuit breaker; they are a device, which when used can automatically switch off the flow of electricity. They are used to protect a piece of machinery or equipment from damage by an overload of electricity.

What is tp isolator?

TP isolator means triple Pole Isolator.


What is difference between spn and tpn mcb db?

TPN MCB means Triple pole Neutral Miniature Circuit Breaker where as SPN MCB means single phase Neutral MCB.


Difference between TP and TPN isolator?

The main difference between the two is that a TP isolator is only a "triple pole" isolator. A TPN isolator is a "triple pole" and neutral isolator.

Difference between on load and off load isolator?

In electrical system load means circuit carrying current . Isolator is device which make on ( Connect ) and off ( Disconnect ) of circuit from supply. When load is ON means carrying current and required to disconnect from supply , than is called on load isolation.Here required on load isolator. When load is OFF means not carrying current and required to disconnect from supply , than is called off load isolation.Here required off load isolator. On load isolators design is more precise than off load isolator because while isolating load during ON states create heavy sparking and transient voltage spikes.

What will happend when isolater will open on load?

An 'isolator' (UK terminology) or 'disconnect' (US terminology) are generally not designed to break a load current. The circuit must first be broken using a circuit breaker. If an isolator were to be opened 'on load', then it's likely to draw an arc which it has no means of breaking. The heat produced by that arc is likely, then, to damage the isolator's contacts.


What is the difference between a line isolator and a bus isolator?

If I'm interpreting the question accurately, a "line isolator" is an insulating standoff for transmission or distribution cable. A bus isolator is an insulating standoff for tubular or bar bus as is normally seen in a substation switching yard.
