Workers Compensation

Workers Compensation (WC) is gradually becoming an important part of employment law in the United States. The laws in the 19th century which implied almost full assumption of risk when an employee would attain a certain job are being replaced with employee friendlier legislature. The old "fellow-servant rule" (Wertheim., F. 1986, NY Law Review,) which came from general common-law princip... More

History

Protection History

Voltage drop relays These relays worked with voltage as additional criteria to current. Since the current is equal over the line, the voltage decreases and reaches its smallest amount at the fault’s location. Voltage drop time relays were equipped with a timing element - a drum made of aluminum, rotating in the magnetic field of an electromagnet excited by the voltage. The bigger the... More
