Impact of Floating Neutral in Power Distribution

Introduction:

  • If The Neutral Conductor opens, Break or Loose at either its source side (Distribution Transformer, Generator or at Load side (Distribution Panel of Consumer), the distribution system’s neutral conductor will “float” or lose its reference ground Point. The floating neutral condition can cause voltages to float to a maximum of its Phase volts RMS relative to ground, subjecting to its unbalancing load Condition.
  •  Floating Neutral conditions in the power network have different impact depending on the type of Supply, Type of installation and Load balancing in the Distribution. Broken Neutral or Loose Neutral would damage to the connected Load or Create hazardous Touch Voltage at equipment body. Here We are trying to understand the Floating Neutral Condition in T-T distribution System.

Abstract reasoning question




Question 1: Identify the missing square

Abstract reasoning tests are designed to be challenging, in order to differentiate between candidates and to identify the maximum performance they are capable of. They usually have tight time scales, and questions that rapidly increase in difficulty. This means that you will need to identify more rules to solve the problems, and that the complexity of these rules is likely to increase.
While there are many permutations of question types and formats, there are some general concepts which are common, and it can be useful to familiarise yourself with these.
