When the sensors report an event, an analysis of the associated waveforms will determine if fault current was present, showing a blown fuse, or a bad switch. Outside of capacitor bank monitoring, sensors are also used for substation monitoring and fault detection.
Conclusions The on-line monitoring method for shunt capacitors proposed in this paper has the following characteristics: (1) This monitoring method is applicable to shunt capacitor banks of all connection types. It can be realized only by using a relay protection device, with no additional device to measure the state quantity.
In addition to the stand alone capacitor bank monitoring application described above, sensors can be installed on a 3 phase feeder to monitor in near real time: 1.) How many times the capacitor operates and 2.) determine if there is a blown fuse or a bad oil switch, etc.
Protective monitoring controls are available for capacitor banks connected Wye-Wye, grounded-neutral capacitor banks, and ungrounded-neutral capacitor banks, as shown in figures 1 and 2. This topic is discussed further below in Protection of capacitor Banks. The above scheme applicable to double Wye-configured banks is shown in figure 1.
The purpose of a capacitor bank’s protective control is to remove the bank from service before any units or any of the elements that make up a capacitor unit are exposed to more than 110% of their voltage rating.
The purpose of this Application Guide is to outline the general purpose of the use case for using the platform to monitor capacitor banks so utilities can maximize their savings. Aclara’s Smart Grid Sensors weigh approximately 5.5lbs and are designed for applications on standard distribution size conductors and neutrals.
