SEL继电器特色应用,SEL综合保护装置连接sel-700g发电机保护继电器过小，介质，或*小学和备份保护大型发电机。sel-700gt提供符合IEEE 1547标准的联络线保护解决方案的分布式发电。增加中性点电压连接提供百分之100个定子接地保护，基于第三次谐波电压测量。连接的中性点电流输入提供了坚实的接地或电阻接地机器的保护。
autosynchronizer取代外部发电机控制和同步继电器与内置的自动同步功能。发电机的频率，电压，相位控制是自动同步的，并连接到电力系统。SEL继电器监测发电机的同步过程中使用发电机启动报告和基于PC的示波器。
SEL继电器电流差动保护比率制动差动元件应用敏感和奔放的元素，随着同步检查，每赫兹元素伏，整个单元保护发电机和升压变压器。可选电流差动元件检测定子故障，使用一个安全的，敏感的电流差动功能。美国SEL电力变压器和CT连接补偿允许机组升压变压器被列入发电机差动区。

Comprehensive Generator Protection—Connect the SEL-700G Generator Protection Relay across small, medium, or large generators for complete primary and backup protection. The SEL-700GT provides an IEEE 1547 compliant intertie protection solution for distributed generation. Adding the neutral voltage connection provides 100 percent stator ground protection, based on third-harmonic voltage measurements. Connecting the neutral current input provides protection for solidly grounded or resistance-grounded machines.
Autosynchronizer—Replace external generator control and synchronizer relays with the built-in automatic synchronizer function. Frequency, voltage, and phase control of the generator are automatically synchronized and connected to the power system. Monitor the generator synchronization process using generator start reports and the PC-based synchroscope.
Current Differential Protection—Apply sensitive percentage-restrained current differential elements and an unrestrained element, along with synchronism check and volts-per-hertz elements, across the entire unit to protect both the generator and the step-up transformer. Optional current differential elements detect stator faults using a secure, sensitive current differential function. Power transformer and CT connection compensation allows the unit step-up transformer to be included in the generator differential zone.  SEL继电器正确的解决方案，SEL*，
