4.20 Step-up and step-down transformer
4.20.1 Step-up transformer
In certain cases, the use of a generator with step-up transformer (called a block) is required. This may be to
adapt to the closest grid voltage or to step up the voltage to minimise the losses in cables and also to bring
down the cable size. The applications where a step-up transformer is needed, is supported by the ML-2. The
functions available in this application are:
1. Synchronising with or without phase angle compensation
2. Voltage measurement displayed
3. Generator protections
4. Busbar protections
