The G2 hardware version routes three-phase input voltages from the Power Potential Transformer (PPT) through an array of four galvanic isolation transformers to step down high-potential waveforms before digitization. All voltage scaling coefficients, flux integration calculations, and phase-angle synchronization routines are bound to the specific firmware flash revision compiled on the master control processor, ensuring deterministic loop tracking and preventing harmonic measurement distortion across the internal system bus.\u003c\/p\u003e\n\u003ch3\u003eComponent Layout and Terminal Mapping\u003c\/h3\u003e\n\u003cp\u003eThe board layout utilizes explicit physical zones for its isolation components and sensor interfaces.
