Objective: Installation & commissioning of 1 x 20/40MVA, 33/11.5kV transformer.
Scope of Work
Design, manufacture and testing of 1 x 20/40MVA, 33/11.5kV, power transformer.
Full in-house routine, lighting impulse, temperature rise, noise test, zero sequence & partial discharge testing also including tank leakage test.
Delivery using a semi-low loader then off-loading via mobile crane and lifted into position.
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.
