Relay protection annual inspection cycle
A general rule of thumb would be to visually inspect every one to two years, secondary injection testing every one to three years, and primary injection every three to five years or on major changes. Primary injection testing takes it one step further by passing actual fault currents through the entire protection chain—current transformers, the relay. Electromechanical and microprocessor relays should receive a monthly visual inspection. Look over the relays and their cases for any physical damage, and check for foreign objects or debris. For microprocessor units, make sure the relay is displaying the correct date and time. Annual visual and. Acceptance tests are generally performed in the laboratory. ABB's knowledge and experience are not limited to relays only, full support for all protection and control relays throughout their entire life cycle.

Fiber Optic Cable Inspection Ring
Fiber Rings are compact launch / receive cables designed to measure the insertion loss of the near-end and/or far-end connection of a fiber optic link using an OTDR. Long lengths of test cables are impractical to transport and use, therefore AFL Test & Inspection designed coiled lengths of 50µm multi-mode, 62. 5µm multi-mode, or single-mode fibre which are conveniently packaged in compact rings. 1) The other portion of a good physical contact between the connectors ferrules is the absence of any type of. Fiber optic inspection microscopes vary in magnification from 30 to 800 power, with 100-400 power being the most widely used range for connector ferrule inspection. Higher magnification is helpful when for inspecting for proper polish and scratches where you are looking for micron-sized defects.
