Capacitor differential protection

2020-02-25 06:56 Principles of Differential Relaying Introduction. Power systems divided into zones of protection E. g. bus, generator, transformer, transmission line, capacitor, motor, etc. Protection systems applied to these may be broadly classified as unit and nonunit protection systems.

Transformer Differential Protection and Control Devices Easergy MiCOM P63x series differential protection devices are designed for fast, selective, shortcircuit protection of transformers, motors, generators and other installations. Models available: Easergy MiCOM P631, Easergy MiCOM P632, Easergy MiCOM P633 and Easergy MiCOM P634. capacitor differential protection

In another scheme of protection of capacitor bank, the star point of a three phase capacitor bank is connected to the ground through a current transformer and a current sensitive relay is connected across the secondary of the current transformer. capacitor differential protection

To form a bank, capacitor units are connected in series strings between phase and neutral, shown in Fig. 4. The protection is based on the capacitor elements (within the unit) failing in a shorted mode, short circuiting the group. When the capacitor element fails it welds and the capacitor unit remains in service. The capacitance of a capacitor is proportional to the surface area of the plates (conductors) and inversely related to the gap between them. In practice, the dielectric between the plates passes a small amount of leakage current. It has an electric field strength limit, known as the breakdown voltage.

It provides sensitive voltage differential and current unbalance protection with compensation adjustment for small voltage differential levels due to variations in individual capacitor elements from manufacturing, PT, or instrument transformer measurement errors. Voltage differential protection method for grounded wye capacitor banks In this scheme, shown in Figure 4, two threephase voltage transformer outputs are compared in a differential relay. Loss of capacitor unit in each phase can be detected independently. Capacitor failures in shunt capacitor banks. Negativesequence differential (87Q) protection has been applied to line protection for more than a decade [1. Recently, it has been applied to transformer protection, primarily for its sensitivity to turntoturn faults [2 [3 [4. The 87Q elements follow the current differential principle,
