HHZ-BPT HHZ-BPT High Voltage Fuses Special Purpose Application Range Types Fuses for Protection of Potential Transformers(PT) SIBA HHZ-BPT series of special purpose fuses are current-limiting class for the protection of potential transformers (PT) based on SIBA s own Company Standard. These specially designed fuses have excellent current-limiting properties with the capability of isolating the faulty potential transformer in a matter of milliseconds from the grid. The fuses are available in 6/12kV, /17.5kV, 20/36kV and 20/36kV, have current ratings from 1A 5A without strikers, available in two diameters, 24mm and 39.6mm with body lengths commensurate to the rated voltage. The first criteria is the system operating voltage, the rated voltage of the fuse must exceed the system operating voltage. Under normal operating conditions, the voltage transformer s load current is usually much less than 1A. The fuse is selected to withstand worst case transients. The transient currents (such as inrush during energizing) should be plotted on the fuses TCC (Time Current Characteristic) curve for determining discrimination. A discrimination safety margin of 1:2 is recommended to avoid nuisanse tripping. NEW - E-Rated fuses per IEEE C37-41 -2008 - Contact SIBA 134
