TIÊU CHUẨN KỸ THUẬT selectivities

complementary technical information Industrial installations without discrimination run a series of risks of varying importance including: c production deadline overruns; c interruption in manufacturing, entailing: v production or finished-product losses, v risk of damage to production machines in continuous processes; c restarting of machines, one by one, following a general power outage; what is discrimination? Discrimination, also called selectivity, is the coordination of automatic protection devices in such a manner that a fault appearing at a given point in a network is cleared by the protection device installed immediately upstream of the fault, and by that device alone c total discrimination Discrimination is said to be total if, for all fault current values, from overloads up to the non-resistive short-circuit current, circuit breaker D2 opens and D1 remains closed c partial discrimination Discrimination is partial if the above condition is not respected up to the full short-circuit current, but only to a lesser value termed the selectivity limit current (Is) c no discrimination In the event of a fault, both circuit breakers D1 and D2 open E26406 natural discrimination with Compact NS circuit breakers E34282 D1 D2 M M Discrimination between circuit breakers used for motor protection Due to the Roto-active breaking technique employed by the Compact NS, the combined use of Merlin Gerin circuit breakers provides an exceptional level of protection discrimination 10 t (s) 1 01 This is the result of the implementation and optimisation of three different techniques: c current discrimination; c time discrimination; c energy discrimination .001 300 100 x 100A BTP555E-4.0110-discrim Discrimination between two distribution circuit breakers c for discrimination between a circuit breaker and a motor control and protection assembly If discrimination is partial, the table indicates the maximum fault current value for which discrimination is ensured For fault currents above this value, the devices trip simultaneously Overload protection: current discrimination Discrimination is ensured if the ratio between setting thresholds is greater than 1.6 (for distribution circuit breakers) Low short-circuit protection: time discrimination Tripping of the upstream device is slightly delayed to ensure that the downstream device trips first Discrimination is ensured if the ratio between the short-circuit thresholds is greater than 1.5 High short-circuit protection: energy discrimination This protection system combines the exceptional current limiting capacity of the Compact NS and the advantages of reflex tripping, sensitive to the energy dissipated in the device by the short-circuit In the event of a high short-circuit detected by two circuit breakers, the downstream device limits it sharply The energy dissipated in the upstream device is not sufficient to trip it, i.e discrimination is total for all short-circuit currents Discrimination is ensured if the ratio between the circuit breaker ratings is greater than 10 D2 M 100 D1 c for discrimination between distribution circuit breakers Combinations providing total discrimination are indicated by coloured zones or the symbol T on a coloured background If discrimination is partial, the table indicates the maximum fault current value for which discrimination is ensured For fault currents above this value, the circuit breakers trip simultaneously D2 1000 how to use the discrimination tables D1 NS100 NS250 100A 250A 10000 c shutdown of vital safety equipment such as lubrification pumps, smoke fans, etc E26366 Protection discrimination is an essential element that must be taken into account starting at the design stage of a low voltage installation to ensure the highest level of availability for users Discrimination is important in all installations for the comfort of users, however it is fundamental in installations requiring a high level of service continuity, e.g industrial manufacturing processes E34281 protection discrimination Merlin Gerin 2-3 requisite conditions The values indicated in the tables (for 380, 415 and 440 V) are guaranteed if the following
