Page 17: Curve Trace Testing
Northern Electric & Power Inc. (NEP) rapid shutdown devices are unique in that they allow for quick and easy performance of the IV curve trace test on a string level without the need to disconnect each rapid shutdown. NEP achieves this by saving the power state of the device, which allows a small safe current to continue traveling through the string when it is disconnected, powering the devices and running the test. -
Page 18: Step-By-Step Guide
Step-by-Step Guide: The following steps should be followed to perform an IV curve trace with NEP RSDs and Seaward IV Curve Testers: Step 1: Turn On the RSD (if system already commissioned, skip to step 2) · Connect all PV-strings to the inverter. -
