| Current Limiting Reactors |
| Current limiting reactors are used to limit the magnitude of fault current within the capacity of the installed equipment. They are connected with the line or feeder to
reduce the short circuit level. |
|
| Application |
| • |
They can be used to limit the inrush currents during Capacitor switching, Motor starting, Transformer inrush currents to limit fault currents in a network. |

Measures, stores and displays voltage and current on all three phases, frequency, power factor, real and reactive power import and export and apparent power. |
| • |
Data logging facility with 32 kB non-volatile memory and date and time stamp. Typical data logging period for 36 days. |
| • |
Provides alerts for UV, OV, OC, low pf, high pf. |
|
|
| Benefits and applications |
| Energy and demand profiling that helps in characterizing disturbances, Monitoring of transformers and motors in distribution and industrial networks to study the loading and loss patterns. Monitoring of industrial networks (main incomer as well as individual feeders) for power parameters monitoring Trend analysis of PQ parameters in order to identify opportunities for energy savings and demand reduction. For energy audits to increase energy efficiency. |
