Figure 2 - Human body ESD test model with ESD-safe Cx added for protection To understand the protection principle behind using these capacitors, consider the typical ESD test circuit shown in figure 2 for the human body model. Rc, Cd, and Rd are specified by the test standard. Cx is the ESD-Safe capacitor added across the device to be protected.
overcurrent device is not required if the capacitor is connected on the load side of a motor-running overcurrent device. Fusing per the Code provides reasonable protection if the capacitors are the metallized film self-healing type. If not, each capacitor should be individually fused as shown in Figure 2. Fusing each individual capacitor is especially important in large banks of parallel

Capacitor Bank Protection— Protect a variety of capacitor configurations, including grounded and ungrounded, single- and double-wye configurations. The SEL-487V has phase- and neutral-current unbalance elements and phase- and neutral-voltage differential elements to provide reliable protection for virtually any application.
This relay protects grounded and ungrounded, single- and double-wye capacitor configurations and allows you to obtain full control of your capacitor banks. Combining these components with capacitor bank protection devices expands their functionality.
Each capacitor or group of capacitors is usually protected by fuses, which are already installed by the manufacturer. Fuses must have an I2t characteristic that will not cause the fuse to blow with the inrush current resulting from the connection of the capacitor bank. Common protection devices of capacitor banks are:
Simplify relay setting and application while reducing inventory by using one relay for all of your capacitor bank needs. The versatile SEL-487V Capacitor Bank Protection, Automation, and Control System can handle grounded and ungrounded, single- and double-wye capacitor bank applications.
Fuses must have an I2t characteristic that will not cause the fuse to blow with the inrush current resulting from the connection of the capacitor bank. Common protection devices of capacitor banks are: HV: High Voltage (V ≥ 60 kV); MV: Medium Voltage (1 kV < V < 60 kV); LV: Low Voltage (V ≤ 1 kV).
When it comes to Power factor, Each phase of a capacitor bank is formed by groups of capacitors in series association for power factor improvement. The 3 phases are then connected in star, being the neutral point isolated or grounded, according to the operation of the network, as shown in Figure 27.
