Objective: Installation & commissioning of 2 x 11,5/23MVA, 33/11kV transformers
Scope of Work
Design, manufacture and testing of 1 x 15/30MVA, 33/11.5kV, power transformer.
Full in-house routine, & partial discharge testing.
The transformer was delivered with radiators attached and conservator removed, using a low loader then off-loading via mobile crane and lifted into position. The transformers was then built up using the same crane.
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.
