Calculation of setting values ​​for distribution network relay protection

Calculation of setting values ​​for distribution network relay protection

This calculator performs basic distribution system protection calculations, including base current, secondary current, plug setting multiplier, and relay operating time. The selected protection principle affects the operating speed of the protection, which has a significant im-pact on the harm caused by short circuits. Calculation Example: This calculator helps in determining the settings and operating time of overcurrent relays in a distribution. This technical report refers to the electrical protections of all 132kV switchgear. [pdf]

Use an optical splitter to connect two network cables

Use an optical splitter to connect two network cables

You use optical couplers and splitters to split or join signals in fiber networks. However, connecting one splitter to another—also known as cascading splitters—can be tricky. Also known as optical splitters, fiber splitters, or beam splitters, these devices are integrated waveguides ensuring wide bandwidth and minimal loss in high-frequency applications. It plays a vital role in optical fiber communication systems, especially in passive optical networks (PONs). [pdf]
