what is main difference between live tank and dead tank
current transformer?
Answer Posted / samiran bairagya
Following are the advantages of Live Tank over dead Tank :
a) The Primary conductor is short than (in live tank CT) than the Dead tank CT which gives better Rigidity and gives high short circuit current withstanding capability and reliability.
b) Primary winding is uniformly distributed around Core, Hence CT is truly low reactance type, which has inherent better transient performance.
c) Due to shorter length and the tank being live the major insulation is not over the high current carrying primary, which is the main source of heat (as in the case of Dead tank type design.) the insulation does not get heated up while dissipating the heat generated. This facilitates much superior thermal stability of insulation and longer life
