what is insulation co-ordination

                      insulation co-ordination

~ power systems have equipment apps operating at different voltage level and each has different level of voltage and each has different levels of voltage wipe standing ,different types of protective equipment to mute against over voltage.

~ All these need to be coordinated , this is called emulation coordination.

~ The following points are looked at in chhakuleshan co-ordination.

~ use positive devices again low voltage 

~ keep the protective device in the system in such a way that the protective device in the system in such a way that protective device is not damaged.

~ in order to do this, the characteristic of the line switch keeper, suns former, mind etc.,

~ of isleman's Franny and the prototype device such as road gash ,lighting arc is co-ordinated.

~ is called contains an instrument that measure protection again groom hotage through a lighting arrester.

~ insulation characteristic of the protective device and equipment.

~ show by the functional curve Q of the protective vice.

~ when the characteristic of the equipment is much higher than the records tick of the protective device.

~ the evaporation of the equipment when the over voltage occurs.
