  • How to use the best-selling fiber optic end-face inspection instrument

    How to use the best-selling fiber optic end-face inspection instrument

    Simply affix the FIP-500 to the connector endface and—in less than 10 seconds—a pass/fail result is automatically obtained and saved without the need for any settings or further manipulation. This fiber optic inspection scope provides automated PASS/FAIL certification take the guess work out of. Microscopes for network maintenance, lab and manufacturing to inspect the end face of single and multi-fiber connectors for scratches, defects and contamination. Even a small dust particle or scratch on the endface can increase insertion loss, reduce return loss, and introduce random link instability. We also offer two scanning white-light interferometers (SWLI) that enable. Inspection and cleaning of fiber optic end faces have been best practices for some time, yet contaminated connections remain the number one cause of fiber-related problems and test failures for data centers, campuses, and other enterprise or telecom networking environments.

  • Electrical Relay Protection Inspection Status

    Electrical Relay Protection Inspection Status

    Do a basic visual inspection of the relay. Many relays have a clear plastic shell containing the coil and contacts. They not only control the flow of power but also incorporate fail-safes that protect systems from overloads and potential hazards. In the domain of electrical equipment manufacturing, any delay or error in relay performance. The testing and verification of relay protection devices can be divided into four groups: Type tests are needed to prove that a protection relay meets the claimed specification and follows all relevant standards. Since the basic function of a protection relay is to correctly function under abnormal. Today, Megger offers the FREJA and SMRT relay test sets, the hardware required to access the IEC 61850 network. The relay isolates the high power circuit, helping to protect the lower power circuit by providing a small electromagnetic coil for the logic. Based on this, this paper proposes a novel relay protection equipment status evaluation strategy.
