The KD/KE-Relay Man Machine Interface (MMI) is a portable, rechargeable battery-powered unit designed to work with KD/KE motor protection relays. MELPRO series line up offers appropriate protection systems for the power distribution systems ranging from high voltage to extra high, and provides products with great precision and reliability suited to the needs of the time. Event records can also be downloaded with the aid of the laptop for further analysis. All the settings are password protected. The relay has an on-board database where time and date. ABB's multiapplication protection and control offering covers the full range of basic power distribution applications, provides complete coverage for advanced power generation and distribution applications, as well as introduces a centralized approach to protection and control in distribution. Protection relays in a Main Distribution Board (MDB) are the decision layer of the power distribution system, coordinating fault clearing, selective tripping, and event reporting across incomers, bus couplers, outgoing feeders, capacitor banks, transformers, generators, and critical process loads. PECO Energy Company, provider of electric power to Philadelphia and the surrounding region, recently rebuilt and renovated a major urban substation. The substation uses a completely integrated protection and control design, comprised of over 140 microprocessor-based relays and communications. Do not use it in humid, overheated, flammable, or explosive environments to prevent accidents caused by improper installation or use. For inductive loads (motors, coils, lamps, etc.
