Voltage Measurement Network parts and their functions
4 top-level parts · 4 parts in total · full bill of materials below
| # | Part | Qty | What it does |
|---|---|---|---|
| 1 | HV Resistor Divider | 1× | 1 MΩ + 1 MΩ divider stepping 240 V down to 120 V, then 120 V to 2.4 V via second stage |
| 2 | Precision Resistors | 1× | 0.1 % tolerance metal-film resistors maintaining accuracy across temperature and supply variation |
| 3 | Voltage Low-Pass Filter | 1× | 1 kHz low-pass RC filter on divider output, rejecting high-frequency noise before ADC |
| 4 | Neutral Reference | 1× | Direct sampling of line-to-neutral voltage and pole ground for single-phase and three-phase variants |
