“…Suppose phase A of Section 3 breaks at the end of the feeder and the load side conductor is grounded with resistance 4 kΩ at t = 0.5 s, the system is arc-suppression coil grounded and the detuning factor p = 0. (18), U dset for sections 2, 3, 10, and 11 is 0.021, 0.13, 6.7e −4 , and 0.01 p.u., respectively. In Figure 15, the VBDV based on phase voltage of Section 3 is about 1.5 p.u.…”

“…For that the ABDVs based on the faulty phase voltage and ZSV are impacted by the fault positions, neutral grounded modes, fault conditions, it is recommended that the fault criterion preferably adopts the ABDVs based on FCPSV and NSV for systems with lack the data synchronization ability. In such systems, the fault detection criterion is similar to (18) and (19). The only difference is that the differential voltage is calculated from the voltage amplitudes rather than the voltage vectors.…”

Single phase line-broken (SPLB) fault is one kind of high impedance fault (HIF). When a SPLB fault occurs, there are four scenarios: SPLB fault with neither side conductors grounded (SPLB-NSCG), with source side conductor grounded only (SPLB-SSCG), with load side conductor grounded only (SPLB-LSCG), with both side conductors grounded (SPLB-BSCG). Traditional HIF detection methods using current or voltage characteristics have low sensitivity to SPLB fault. In this paper, voltage characteristics are analysed firstly in the cases of the first three scenarios of SPLB fault, respectively. Theoretical analysis finds that the voltage at both the sides of the disconnection point is significantly different. A high sensitive SPLB fault detection method based on differential voltage is proposed for radial distribution network with different data synchronization ability. Finally, SPLB fault location methods based on centralized intelligent mode feeder automation (FA) and intelligent distributed mode FA are proposed. Simulations based on PSCAD verify that the proposed SPLB fault detection method is feasible, highly sensitive and immune to the neutral grounded mode, fault scenarios and fault resistance.

“…Many protective device vendors leverage the precise timing of local and distant measurements to quickly switch lines out of service, thereby preventing a larger scale outage and allowing the power system to continue operating. Under the right deployments, this can include detecting and isolating falling conductors before they reach the ground [31], which can prevent larger scale electrical disturbance and secondary impacts, such as wildfires, that would affect larger infrastructure.…”

With the advent of a new Precision Time Protocol specification, new opportunities abound for clock synchronization possibilities within power grid control systems. The third iteration of the Institute of Electrical and Electronics Engineers Standard 1588 specification provides several new features specifically aimed at complex, wide-area deployments in which situational awareness and control require precise time agreement. This paper describes the challenges faced by existing technology, introduces the new time distribution specification, and provides examples to explain how it represents a game-changing innovation.

“…Downed conductors may not contact a conductive object and, therefore, have good probability of remaining energized. It's not easy to find fault [1][2][3][4][5] and at present this fault comes under open-circuit fault. This paper mainly concentrated on location detection of Downed or Broken power line Fault not touching the ground.…”

Faults occurred in power system are common, all these faults are detected by protective devices but faults like Downed or Broken power line Fault not touching the ground, these faults not having enough faults current to operate fault detection devices in Over Head power distribution. Till now there is no protecting devices are identified this type of fault and location of this fault. As of now identifying by only by visual sighting. The proposed solution for finding Fault location Downed or Broken power line Fault not touching the ground.
