How to use the K266 relay protection tester

The steps for operating a relay protection tester can be divided into the following stages: ✅ Preparation: ⇨Make sure the tester is connected to a 220V AC power supply and is reliably grounded. In this way, you will always be at a loss when you encounter difficult problems. Let's use the specific method of relay protection! 1. Wiring instructions The. Before the test, the voltage of the side to be combined does not meet the condition of the same cycle (lower or higher than the voltage of the system side), if the frequency meets the condition but not equal, the angular difference energy on both sides can be turned on and off periodically. The. The relay tester is the best device for checking the operability of these protective devices. Prior to the discussion on the. Traditional protective relay books are written by engineers as a resource for engineers to use when modeling the electrical system or creating relay settings, and they often have very little practical use for the test technician in the field.
