Product Overview
L/C Magnetics is a single phase high current transformer manufacturer. The customer is looking for a 120 KVA single phase transformer with 600 VAC, 200 Amps primary and 30 VAC, 4000 Amps secondary output. It is really hard to build this transformer, so we suggested our customer to use three 40 KVA single phase transformers to get 120 KVA. The primary sides of the three 40 KVA single phase transformers are connected in parallel. The secondary sides of the three transformers are connected in series with a common bus bar.

The 120 KVA transformer consists of three 40 KVA transformers (T1, T2, T3), P/N 18699B with connections as shown below:
Specifications of the 120 KVA transformer:
- High Current Transformer: 120 KVA, 1 PH, 60 Hz
- Primary: 600 VAC, 200 Amps
- Secondary: 30 VAC, 4000 Amps
- Primary copper bus bars are 1/4” x 1” with two holes
- Copper winding construction
- Estimated weight: 2100 lbs approx.
- Customer is responsible for secondary bus bar.
- Customer is responsible for mounting plates for T1, T2 and T3.
- Customer is responsible for parallel connections of T1, T2 and T3 on the primary side.
One Common bus bar thru T1, T2 and T3 will yield 30 VAC, 4000 Amps as shown below. Three P/N 18699B (40 KVA) are used to build one 120 KVA transformer.
