Objective: Installation & commissioning of 2 x 7.5/15MVA, 33/11.5kV transformers
Scope of Work
Design, manufacture and testing of 2 x 7.5/15MVA, 33/11.5kV, ONAN/ONAF power transformer.
Full in-house routine, & partial discharge testing.
Delivery using a short file steerable trailer for site access then off-loading via hydraulic jacking and skating including rotation of unit and a one directional skid of 13m.
Full commissioning works as per the customers specification which includes; insulation resistance of each winding, core & secondary circuits, transformer ratio check, vector group check by 3 phase low voltage energization of transformer, checks on all CTs & VTs for insulation resistance, ratio & magnetization curves, operation of tapchanger through range & operation of limit switches, operation of protection equipment, oil sampling for routine, water & dissolve gas analysis.
