With the current transformer protection main and relay device, in line with short-circuited overload, etc, to relay device fault signal fault electric protection provide cut off with current transformer

Road, in order to protect the safety of the power supply system. Protection with micro current transformer working conditions and measurement in transformer protection, with completely different than normal current transformer is in grade are a few times when the current times begin to work effectively. With the main transformer protection requirements: 1, insulation and reliable, 2, large enough accurate limit coefficient, 3, enough heat stability and the dynamic stability. With transformer protection in full load can meet the magnitude of accurate under one of the greatest current requirements that rated accurate a current limits. Accurate limit coefficient is rated a current and accurate limits rated a current ratio. When a current when big enough iron core will be saturated up less than reflect a current role, accurate limit coefficient is said the characteristics. With transformer protection level 5 P, accurate *0 P, said in a current rated accurate limits the permissible error 5%, *0% and, the impact of the fault line current to produce heat and electromagnetic force protection, with current transformer have to bear. The secondary winding, short circuit current transformer in a second and can bear no damage of a current RMS, says short hot current rating. The secondary winding, short circuit current transformer can bear and no damage a current peak, says the rated current dynamic stability. With the current transformer protection is divided into: 1, overload protection, 2, current transformer differential protection current transformer, 3, grounding protection current transformer (zero sequence current transformer)
