It has been observed that the presence of DC bias currents/fluxes in power transformers generates harmonic currents and voltages with an associated increase in reactive power (kVAr) demand resulting in a voltage drop. Such DC biases can occur: in tra

An assessment of the transient environment for protective relays produced by high-altitude electromagnetic pulse (HEMP) events is presented in this paper. Several mechanisms for coupling of HEMP to relay terminals are used to develop estimates of pos

Since 1983, the US Department of Energy has been actively pursuing a research program to assess the potential effects of one or more electromagnetic pulse (EMP) events on the nation's electric energy supply. A nominal EMP environment suitable for ass

An approach to the computation of the electromagnetic field reflected from a lossy half-space directly in the time domain is discussed. This approach requires first evaluating the impulse response of the half-space and then convolving it with the spe

A protective relay system, subjected to a high-voltage, steep-front impulse, has been shown to fail in the laboratory via flashover-induced current follow through on the DC power supply. Laboratory experiments were performed to characterize the respo

A scenario in which, seconds after a high-altitude nuclear event, the Earth's surface experiences a very low-frequency, quasi-DC magnetohydrodynamic electromagnetic pulse (MHD-EMP) field is considered. MHD-EMP fields impress quasi-DC currents on tran

Transformers in power electronic circuits are inadvertently but frequently exposed to direct current (DC) bias due to circuit imperfections. Such undesirable bias currents occur, for example, in power system transformers near high voltage DC terminal
