Abstract:
In distribution 6–10 kV networks with an insulated neutral for earth fault protection, zero sequence current directional protection devices are commonly used. According to the operation data, the main disadvantage of such kind of protection is the possibility of their functioning failures in transient conditions with the most dangerous for network intermittent arc earth faults. It is known that most earth faults in 6–10 kV networks, primarily in the initial stage of insulation damage, have an intermittent arc. Operation failures of zero sequence current directional protection in case of arc fa

Abstract:
Overcurrent and earth fault protective equipment employing time grading and directional detection cannot provide correct discrimination on all power networks and in many cases clearing times for some faults would not be acceptable. Differential protection is an alternative overcurrent protective scheme, which is used to protect individual sections of networks or pieces of equipment, such as transformers, generators, e.t.c. Thus, where protection co-ordination is difficult using time delayed over current and earth fault protection, or where fast fault clearance is critical, then differential pr

Abstract:
This work aims to study relay protection and automation in insulated neutral networks to identify additional criteria for choosing the type of earthing. To calculate the single-phase earth fault currents as a function of the operating modes of the electrical substation, the 10 kV network of the electrical substation was simulated in the software package. The advantages and disadvantages of centralized and non-centralized protections are shown. The paper presents the sequence of actions necessary for the correct operation of directional zero sequence protection.

Abstract:
A novel algorithm is proposed for the purpose of improving the reliability and sensibility of fault component identification of wide area backup protection. The algorithm, called earth impedance comparison protection (EICP), is realized by comparing the ratios of different nodes, and the ratio is obtained by the bus voltage to the differential current. The advantages of EICP are verified in this paper using the measurement function of wide-area measurement system. The results of case studies show that EICP is superior to the current differential protection in terms of the sensitivity and to th

Abstract:
The substation is one of the components in the electric power distribution system which plays a very important role because it is the connection between electricity services to customers. In the electric power distribution system, there are disturbances that often occur, one of which is a short circuit. For that, the way to overcome this is using the Distance Relay protection system, OCR / GFR and DEF. The purpose of writing this research is to determine the value of setting relay distance, setting Over Current Rele and Directional Earth Fault relay in order to secure the 70 kV transmission ne

Utfört examensarbete undersöker vinkelfelet i mätkretsen för riktade jordfelsskydd och hur det påverkar dess felbortkoppling. Uppkomna vinkelfel i mätkretsen kan påverka det riktade jordfelsskyddet så att verklig felström och uppmätt felström inte stämmer överens, vilket kan leda till uteblivna eller obefogade felbortkopplingar. Vattenfall ställer krav på att vinkelfelet får uppgå till max ±2 grader för mätkretsen. Eftersom vinkelfelet i många fall har en hög påverkan på jordfelsskyddets noggrannhet undersöks vad Vattenfalls vinkelkrav egentligen innebär. Största orsaken till vinkelfelet uppst
