2 What are the potential negatives of WDT’s new JIT system in terms of limiting customer choice and short-circuiting the design process? Sid Beckett, the Managing Director of Wiltshire Distribution Transformers (WDT), had concentrated on a new generation of simplified, modular designs that used proven US technology. He had energetically exploited the market advantages this had given. WDT now has two major product ranges:

● TR 100: 3-phase, oil-cooled transformers with a power rating from 200 to 2000 kVA;

● PS 300: packaged substations that utilise TR 100 transformers with appropriate switchgear and LV control panels.

Judging by the number of enquiries, the market for both product ranges was now increasing.
