Power Measurement Instrument for Microcomputer Relay Protection
The microcomputer protection relay tester (also called relay protection tester) is a critical intelligent device for modern power systems. Meet all test requirements on site. The instrument has standard four phase voltage and three-phase current output. It combines measurement, testing, and analysis functions to ensure safe. As someone who has been dealing with substations and power equipment for a long time, when choosing a relay protection testing instrument, the core factor is: it must precisely match the type of protection you want to test and also be compatible with the voltage level at the site. It is produced by referring to Technical Condition for "DL/T624-2010" Microcomputer Relay & Protection Test Device issued by the original Power Department, extensively listening. 3 phase protection relay test set for industrial control computer, with 110V and 220V dedicated adjustable DC power output, 2 USB ports and RS232 porthigh-tech design, compact and lightweight.

Principle of Optical Power Meter Measurement of Absolute Value
An optical power meter works by converting incoming optical energy into an electrical measurement through a photodiode detector. The detector senses the light level, and the meter displays the result in the selected unit. Newport's 1936/2936-R Series Optical Power Meters are among the most versatile power meters in the market, and the. An optical power meter (OPM) is a device used to measure the power in an optical signal. Industry guidance commonly describes dBm as power referenced to 1.
