  • Page 83 Technical catalog for Susol & Metasol ACB 1. Protective Coordination The recent development on low voltage protective device is on steady increase in quantity and high breaking capacity achievement is on the way by breakthroughs in technology to accommodate larger power supply system. Result from these process is a development of over 6000A product type and 150kA breaking capacity circuit breaker to satisfy requests from bigger power supply system.
  • Page 84 Protective Coordination 2. Selectivity Techniques There are three basic approach to build power protection system; fully rated, discrimination, and cascading (series -combination rated). Common goal of different approach is to protect system and machineries, yet installment expenses or continuity of power supply under accidents have discrepancies for each approach. Fully Rated Protection In fully rated system, every breaker is arranged to operate independently on its own rating.
  • Page 85 Technical catalog for Susol & Metasol ACB By utilizing discrimination system, continuity of electricity supply can be maximized. Fully rated system require every breaker to have breaking capacity that can cover maximum fault current. However by applying discrimination system, breaker that is the closest to accident point will only be operated to disconnect the fault block from its power system.
  • Page 86 Protective Coordination 2. Selectivity Techniques 3. Time Selectivity Time selectivity is achieved when upstream breaker has longer time delay than downstream breaker about the same accident current. The optimum arrangement of this system can be organized with upstream breaker’s electronic trip unit which can perform short time delay setting. Upstream breaker should be able to perform time -delay function long enough for downstream breaker to eliminate the accident.
  • Page 87 Technical catalog for Susol & Metasol ACB ZSI (Zone Selective Interlocking) This ZSI technique allow breakers to exchange communication signals and to provide more precise discrimination at upstream trip unit level. For instance (see picture 6), ZSI technique is applied to D2 and D1, and hypothesize that both trip units detected the fault in downstream area.
  • Page 88 Protective Coordination 2. Selectivity Techniques IDMTL (Inverse Definite Minimum Time Lag) IDMTL (shown on picture 8) is a method to select a degree of slope under long time delay range. Picture 8. Characteristics of IDMTL IDMTL is used to improve breaker’s discrimination ability under overload protecting area. Not only long time delay characteristic curve’s trip threshold can be changed but also degree of slope can be adjusted during its time delay area.
