Schweitzer Engineering Laboratories, Inc. has announced three new additions to the popular SEL-787 family of differential protection relays, providing low-cost, versatile transformer differential ...

Single-ended signals are very common, but increasingly signal paths are being converted to differential signals as part of the signal chain. The benefits of differential signaling are particularly ...

Using a transformer coupled differential inverting amplifier stage can give a very low input referred noise voltage or Noise Figure (NF) with exceptional SFDR/mW. The NF equation needs to include ...

Since the early days of electric power systems, protection has been essential for the operation and safeguarding of power system assets as well as the safety of its users. Developed for the ...
