Simplify relay settings and application while reducing inventory by using one relay for all of your capacitor bank needs.

Simplify relay settings and application while reducing inventory by using one relay for all of your capacitor bank needs. The versatile SEL-487V Relay can handle grounded and ungrounded, single- and double-wye capacitor bank applications.

Capacitor Protection Control System

This paper provides a quick and simple way to calculate the out-of-balance voltages (voltage protection) or current (current protection) resulting from failed capacitor units or elements.

Principles of Shunt Capacitor Bank Application and Protection

This paper analyzes various capacitor bank configurations and proposes an economical method to help locate the faulty elements or units for each configuration. The paper also provides results that verify the proposed methods using a Real Time Digital Simulator.

Minimizing Capacitor Bank Outage Time Through Fault Location

This course is designed for utility and industrial protection engineers and power system consultants. This two-day course provides hands-on application and settings guidance for the SEL-487V capacitor protection relay. APP 487V includes calculating voltage differential and current unbalance levels using IEEE C37.99-based software and data from capacitor bank examples to develop protection settings. Students (in groups of two) will work directly with an SEL487V Capacitor Protection and Control System to configure system data and determine protection settings.
