: Configure these based on your specific field transformers (e.g., 400:5 CT ratio would be 80:1). Load Profile Recorder
Supports modern Ethernet-based substation architecture for real-time data exchange.
Optional 5-inch color touchscreen for intuitive local interaction.
It exceeds ANSI C12.20 Class 0.1 and IEC 62053-22 0.1 S requirements, with a typical accuracy of 0.02% . sel 735 manual
The SEL-735 Power Quality and Revenue Meter offers Class 0.1 accuracy for billing and advanced monitoring, supporting high-resolution waveform capture and multiple communication protocols. Key installation steps include ensuring proper CT shorting, correct polarity for input connections, and utilizing acSELerator QuickSet software for system configuration and scaling. For detailed technical specifications and installation procedures, consult the official SEL-735 manual.
The SEL 735 relay is a powerful and versatile protection relay designed to provide advanced protection and control for power systems. By following the guidelines and recommendations outlined in this manual, users can ensure reliable and efficient operation of the relay and the power system as a whole.
Adheres to IEC 61000-4-30 Class A requirements. This ensures uniform measurement across varying electrical infrastructure networks. Hardware Configuration & Wiring Forms : Configure these based on your specific field
Widely used by electric utilities for robust, time-stamped SCADA telemetry.
The user interface allows for immediate, on-screen viewing of real-time waveforms, phasor diagrams, and alarms.
It records disturbances, ensuring that users can analyze the root cause of power quality issues. It exceeds ANSI C12
Installation and wiring instructions are foundational. The manual must include mounting dimensions, environmental ratings, power supply requirements, grounding recommendations, and detailed terminal diagrams. Clear wiring examples for current transformers (CTs), potential transformers (PTs), breaker trip and close circuits, and communications interfaces (Ethernet, serial, fiber) reduce installation errors and improve safety. Safety warnings and lockout/tagout procedures must be prominent and unambiguous to protect personnel during installation and maintenance.
Freezes billing quantities during testing, allowing for safe calibration without altering revenue data.
