摘要： A mechanism is described for determining whether or not a ground connection is properly earthed. The mechanism comprises a current measurement transformer configured to detect the sum of currents flowing through one or more live conductors and a neutral conductor and a module for indicating whether the sum of currents is below a predetermined threshold. An output below the said threshold is indicative of the absence of a ground connection.

摘要： To detect accurately an insulation fault in a load circuit (20). Power supply lines (L1,L2) and an electric heater (a load circuit (20)) are connected by a detecting portion (11) to detect a detected voltage Vd (detected value) in accordance with the magnitude of a leakage current Id that flows through a ground GND between the power supply lines (L1,L2) and the electric heater (20), and an evaluation as to whether or not there is a breakdown of insulation of the electric heater (20) relative to the ground GND is performed by an evaluating portion based on the detected value Vd obtained when the relay contact points (21,22) are open.

摘要： The invention relates to a protective device (2) having a circuit breaker (3) for an electrical connection between a transformer (1) and a load (V), wherein an overcurrent device is arranged between the transformer (1) and the load (V), which overcurrent device has first magnetoelectric transducers (4) arranged at each phase conductor (Ll, L2, L3) and the neutral conductor (N), wherein the overcurrent device uses the transducer currents to in each case establish the presence of a first ground-fault current, and wherein the circuit breaker (3) has a switching device, which interrupts at least the phase conductors (Ll, L2, L3) between the transformer (1) and the load (V) in the event of the presence of a first ground-fault current (unrestricted earth fault). In order to also be able to determine the ground-fault current between the transformer (1) and the circuit breaker (3), the invention proposes providing in each case second magnetoelectric transducers (8) at each phase conductor (Ll, L2, L3), the neutral conductor (N) and a star-point conductor (9) which is connected to the star point, using the transducer currents of the second transducer (8) in each case to determine the presence of a second ground-fault current (restricted earth fault), and forming a signal for disconnecting the transformer (1) in the event of the presence of a second ground-fault current.

摘要： An apparatus for detecting a ground fault occurring in a power system which furnishes an AC power from a variable-voltage variable-frequency power supply to a load via a voltage transformer. The apparatus compares a zero phase sequence current with a reference value and, upon detection of occurrence of a ground fault, produces an output signal representing the ground fault. Prior to such comparison, the zero phase sequence current is so processed as to be independent of the frequency of the power system or the reference value is so processed as to be dependent on the said frequency.
