Programming Example

UPS Transfer Time Measurement

The following programming example illustrates how to use the ac source with the Dual Power Analyzer Option 020/022 to measure transfer time on a UPS. Transfer time is defined as the time it takes a UPS to go from online-operation to battery-backup operation when the ac line fails.

This example starts with the ac source output voltage (UPS input voltage) at 120 Vac. The UPS output voltage is connected to a load and to the Power Analyzer input. The ac source output turns on at 120 Vac, then does a 50 ms dropout to 0 volts. Both the dropout and measurements are triggered at the same time. The FETC:TVOLT:ABS? command is then used to return the transfer time, here defined as the time between the start of the dropout and the time when the absolute value of the UPS output voltage exceeds 50 volts for at least 0.001 seconds.
