2014年5月2日 · How to determine the ground fault pickup (50G) of GE369 Multilin relay for MV motor fused starter unit (300HP) at 4.16kV. The ground CT used for sensitive earth fault detection is 50/0.025 for high resistive grounded systems.

2023年11月1日 · We report a biocompatible nanomedicine (GFCT) that possesses both H 2 O 2 self-supply and GSH-elimination properties for achieving highly synergistic enhanced CDT and chemotherapy effects by integrating iron-doped calcium phosphate nanoparticles with hypoxia-sensitive prodrug (tirapazamine).

纳米治疗药物（GOD-FeCaP@TPZ，缩写 GFCT）是通过温和的一步生物矿化过程制备的，使用酶催化剂葡萄糖氧化酶（GOD）作为模板，形成可生物降解的铁掺杂磷酸钙纳米颗粒，然后负载前药替拉扎明（TPZ）。

2005年4月28日 · In most SEL relays, there are two different ways to measure ground fault current. One way (SEL relay word 50N) uses the current as measured by a core-balance CT physically wired to the In terminals. The other (50G) uses the mathematical summation of the three phase CT's.

Designed to enhance the reliability and efficiency of power systems, this state-of-the-art device is essential for detecting ground faults quickly and accurately, The GFCT operates by continuously monitoring electrical currents and identifying discrepancies that indicate potential ground faults, providing critical real-time data to prevent ...

The attached diagram shows a typical LTMR controller installation using a ground fault current transformer (GFCT). Published for: Schneider Electric India

2013年9月29日 · g是指的重力加速度，大小是9.8m/s^2具体力量是多大，要看受力物体的质量，力等于ma=m*50g，也就是相当于受力物体重量的50倍

Ground-fault protection provides protection against phase-to-ground fault, which is more sensitive than protection based on phase current only. It is generally used in TN-S systems but could also be used in other earthing systems. NOTE: Ground …

2024年4月25日 · 50G PON的下行速率，当然就是50Gbps（相比上一代提升了5倍）。 这是OLT侧单口的速率，经过ODN分光，到用户这边，肯定不能承诺是50G。 一般来说，说是万兆（10Gbps），问题不大。 上行速率方面，ITU定义了12.5G/25G/50G三种速率（本来还有10G，离12.5G太近，被抛弃了）。 50G上行/50G下行，叫对称50G PON。 12.5G上行/50G下行、25G上行/50G下行，叫非对称50G PON。 这个和以前的叫法习惯是一样的。 按照行业的设 …

2024年3月26日 · 四川光恒通信技术有限公司此次发布50G PON 三模Combo OLT小型化光器件，为MPM（内置合波）3代波分方式共存，即G/XG (S)/50G三模MPM。 该方案优点是可以复用传统网关设备，同时无需变动/升级用户侧，同时可以优化升级过程、节约设备占用、节省机房空间、降低能耗。 此三模Combo OLT小型化光器件采用新颖光路设计及小型化TO-CAN封装方案，运用光恒公司多年来在同轴封装领域的技术积累和品质管控，将精密制造、多波长合分光设计、各 …
