Reactance CsanyiGroup. protection, backup to busbar protection, reverse zone I. INTRODUCTION A bus differential protection is applied for protection of busbar against bus faults. Looking at the various reports of past occurrences in our network; there are many occurrences involving non operation of bus bar protection schemes. Any case of such non operation, 1., This protection can be further enhanced by combining the fuses with low voltage protection systems or with an overcurrent relay. Selection table Depending on the equipment to be protected and its voltage rating, the table below gives the range of fuses which are best suited to the protection application. Voltage (kV) Motors Power transformers.
