why we use DO Fuse in H.T. Line ? What is the purpose of
DO Fuse
Answer Posted / k.sudheer
DOLO fuses-
1. Avoids loose contact due to spring loaded 'clip' system to the stationary upper portion.
2. Once fuse is blown, the fuse rod 'hangs' down (since the sprint latch was ties by the fuse
wire itself.
3. blown fuse rod can be removed without 'line clear' by using a 'fuse link rod'. Fuse is the replaced at ground, and again using the fuse line rod, install back- "click" the top latch holds.
4. The DOLO fuse rod is a hollow tube of Mica sheets to prevent molten fuse wire from splashing out.

3 shows a 415 V, 3-phase generator supplying a 3-phase 415/110 V transformer. Draw the individual and combined impedance diagrams to a base of 10 kVA. Determine the system fault kVA and the fault currents at the 415 V and 110 V busbars for short circuit faults on the transformer input or output terminals. Work in p.u. values of impedances.
