Integrated Measurement of Multi-Channel-Current Flowing into Single Load

There are various plasma applications of MTF in which very high currents are delivered using modules of capacitor banks to a single load as per the load requirement. Moreover there are other applications too, in which the large number of transmission lines feed a load from a single high-energy capacitor because of their well-defined current ratings. In such type of applications, the total current measurement at load may not be a safe practice for diagnostic equipments involved, as well as there may be space constraint also to put such system. For these applications we are reporting an integrated current measurement system consisting of similar current transformers through which each channel of current is threaded and the instrument itself adds the net output directly, without any electronics involvement to avoid electromagnetic noise pick-up. These current transformers are air cored to avoid any saturation and hence any non- linearity in output thereafter. The former is made of nylon, which is nonmagnetic and serves as air core. The theoretical as well as basic experimental results are given in this paper.
