SEL-07870X1A3A0XCA820630Generator protection relays can be applied to large, medium, and small generators to provide complete protection for both the main and backup generators. SEL-0787 provides a compliant generator grid protection solution for distributed power generation. Adding a neutral point voltage connection can provide 100% stator grounding protection based on third harmonic voltage measurement. Connecting the neutral line current input first * first * first * first * first * first * first can provide protection for machines that are directly grounded or resistor grounded.

Automatic synchronization: Using the built-in automatic synchronizer function to replace external generator control and synchronizer relays. The frequency, voltage, and phase control functions of the generator are used to achieve automatic synchronization and grid connection with the power system. The generator start-up report and PC synchronous oscilloscope are used to monitor the synchronization process of the generator.
Current differential protection: Sensitive ratio braking current differential elements and differential quick break elements are used throughout the device to protect the generator and booster through synchronous detection and overexcitation detection (V/Hz). The optional current differential component detects stator faults through a safe and sensitive current differential function. The power transformer and CT connection compensation allow the booster of the device to be included in the differential protection zone of the generator.
Circuit breaker wear monitoring - using the monitoring function of the circuit breaker to record the accumulated wear of the circuit breaker contacts. This function uses the manufacturer's specifications to define the operation and operation limits of the circuit breaker. The internal monitoring function records the total number of closing/opening operations and integrates the intermittent current of each phase. Set an alarm to alert the operator when the measured and accumulated quantities approach the maintenance threshold. This information helps to proactively maintain and replace circuit breakers, so as not to waste resources.

Model Case Analysis
The SEL microcomputer protection and measurement device adopts DSP, surface mount technology, and flexible fieldbus (CAN) technology to meet the requirements of different voltage levels in substations, achieving coordination, digitization, and intelligence of substations. This series of products can complete functions such as protection, measurement, control, regulation, signal, fault recording, electric degree acquisition, low current grounding line selection, and low cycle load shedding for substations, making the technical requirements and internal wiring of the products more standardized. The product adopts a distributed protection and measurement device. It can be installed in a centralized or decentralized manner, and can also be configured according to user needs to meet different requirements.
The microcomputer protection device is suitable for protection, monitoring, and measurement of voltage levels of 110KV and below. It can be used for line, voltage, capacitor, motor, bus PT detection, backup power automatic switching circuit, and protection, control, and monitoring of main equipment. The modular design not only makes it convenient to equip with secondary equipment, but also enables centralized screen assembly and control. The standardized fieldbus connection C supports coordinated work among multiple nodes, achieving system level management and comprehensive information sharing.
