SELECTION OF CURRENT TRANSFORMERS & WIRE SIZING IN SUBSTATIONS Sethuraman Ganesan ABB Inc. Allentown, PA ABSTRACT More and more sub-stations are retrofitted with numerical relays, meters and monitoring devices. Therefore, we size the protective device as follows: 30,000VA ÷ (480V x 1.732) = 36A x 2.5 = 90.2A The cartoon, for example, shows Prime, Megatron and Soundwave as about the same height, Seekers and Autobot cars as slightly shorter (though not as much as the toys are), and Minibotsas smaller yet. Several methods exist to size current transformers. below. In that case, you’ll probably need to replace your transformer, and when you do, you’ll need to … Transformer Rating = 50 kVA = V 1 × I 1 = V 2 × I 2.
