| On increasing the generator output line voltage |
| (1/1) |
| TiredOldDad:
Here's a thought experiment... Our grid voltage is 230V nominal. I have a portable generator that is preset to output 220V. I want to raise the generator voltage to 230V to match the grid voltage.... no other specific reason. The generator uses an automatic voltage regulator (AVR) with a trimmer pot to vary the field voltage. Increasing the field volage raises the main stator output voltage and vice versa. That said, increasing the main stator output to 230V is a trivial task. Appliances are rated for 220-240V. Questions: 1. Will this inadvertently harm, or at the least, add stress to the generator? (ie. More/less heat? De-rate it? More/less efficient?) 2. Given that the appliances are rated to operate between 220-240V, how does increasing the line voltage from 220V to 230V affect the following, either significantly or subtly: a. Resistive loads? (heaters, incandescent lamps) b. Inductive loads? (fans, A/C compressors) In other words, will any of these types of appliances be more (or less) efficient at the stated higher voltage? |
