MTR-4P多功能保護(hù)繼電器是專為使用作為一個獨立的保護(hù)和測量裝置或在單相或三相電力網(wǎng)絡(luò)，需要船舶批準(zhǔn)大型應(yīng)用解決方案的組成部分。
DEIF隆重地推出一款**型多功能保護(hù)繼電器MTR-4P，它可代替多個單功能保護(hù)繼電器。MTR-4P可使用DEIF的特有的PC工具快速進(jìn)行配置，與傳統(tǒng)解決方案相比，具有成本低廉和靈活性強的特點！ MTR-4P不僅非常適合獨立的保護(hù)，也可作為需要船級社認(rèn)證的單相/三相電網(wǎng)的一部分。
可編程MTR-4P繼電器具有快速、簡單和多功能等特點，可按下述六種不同邏輯類別提供多達(dá) 13 種不同的保護(hù)功能，六種類別為：電壓、電流、頻率、不對稱性、負(fù)載和主電網(wǎng)失電 (LoM)。使用MTR-4P代替 5-10 個單功能保護(hù)繼電器可以實現(xiàn)無縫對接！
MTR-4P還可測量和計算50余種參數(shù)，例如交流電壓、交流電流、有功/無功視在功率、功率因數(shù)、頻率、kWh、kvar、諧波總量、動態(tài)和*大需量。MTR-4P配有通用電源，可承受高達(dá)1000 V L-L的高交流電壓和高達(dá)20 A的電流輸入。
從故障出現(xiàn)到跳閘的通常響應(yīng)時間小于50ms。因而，MTR-4P可作為改造項目的替代產(chǎn)品，甚至可作為靈活的備件，輕松靈活地安裝在新設(shè)備中。調(diào)試人員僅需連接一個USB 2.0接口即可快速、輕松配置所有參數(shù)和輸出。

獲得DNV GL船級社認(rèn)證
Fast, simple and multi-functional, the programmable MTR-4P protection relay offers up to 13 different protection functions in six different logical categories: Voltage, current, frequency, asymmetry, load and loss of Mains (LoM). Simultaneously, the MTR-4P can be used as a dedicated measuring point reachable by communication and capable of measuring and calculating more than 50 parameters such as AC voltage, AC current, active/reactive apparent power, power factor, frequency, kWh, kvar, THD, dynamic and maximum demands.
MTR-4P is designed for use as a stand-alone protection and measuring unit or as component in large application solutions on single-phase or three-phase electrical power networks that require marine approval.
Featuring a universal power supply, the MTR-4P withstands high AC voltage inputs of up to 1000 V L-L and currents of up to 20 A. The typical response time less than 50 ms, from error occurs to trip. This makes the MTR-4P flexible and easy to install in new buildings, as replacement in retrofit projects, or even as a flexible spare part. Simply connect a USB 2.0 interface for fast and easy configuration of all setting parameters and outputs.
