Thông tin sản phẩm

- Achieve Complete Capacitor Bank Protection and Control With One Relay
Protect and control grounded and ungrounded, single- and double-wye capacitor bank applications with a single relay. The SEL-487V includes both voltage differential and overcurrent elements for complete protection.


- Provide Flexible Multibank Protection and Control
Provide sensitive capacitor failure detection with application-based settings that provide voltage and current unbalance elements. Select from voltage, power factor, VAR, or time-of-day/day-of-week control schemes. Prevent equipment damage to capacitor banks and switching apparatus using control instability (hunting) detection.


- Automatically Sequence Capacitor Banks
The new universal sequencer available in the SEL-487V-1 replaces SELogic control equations or an external programmable logic controller (PLC). It automatically sequences up to three capacitor banks on and/or off, based on which capacitor bank has accumulated the most operations. SELogic-based settings allow a variety of inputs for the sequencing variable, including time, number of operations, kVARs, and fixed (1, 2, 3). It is also possible to reset and preload functions.


- Simplify Settings Calculations
Automatically perform calculations for application-based settings using IEEE C37.99 specification settings assistant software.


- Improve Power System Reliability and Stability With Built-In Synchrophasor Measurement System
Obtain real-time measurements of electrical quantities. Provide local control based on wide-area measurements.


-Save Time Identifying Faults
Find faulty capacitor units using the patented advanced faulted phase and section identification logic.
