Electroporation of rapeseed protoplasts – transient and stable transformation

Physiologia Plantarum, 1993
Protoplasts of Brassica napus hypocotyls were transfected using electroporation. Parameters such as discharge potential, protoplast density and buffer constituents were tested to determine the most suitable conditions for gene transfer. To monitor the introduction of DNA into protoplasts a plasmid containing the β‐glucuronidase (EC 3.2.1.31), and the ...

Transient Compensation of Current Transformers

IEEE Transactions on Power Apparatus and Systems, 1978
The existence of a siqnificant exponentially decaying dc transient in the primary current of a conventional current transformer leads to large transient values of core flux. Protective scheme design is therefore subjected to constraints, either that ct saturation be tolerated or that larger ct's incapable of saturation be provided.

Nonlinear transient simulation of transformers

IAS '95. Conference Record of the 1995 IEEE Industry Applications Conference Thirtieth IAS Annual Meeting, 2002
In this paper, a nonlinear model of a power transformer which takes into account both the saturation and the hysteresis is proposed. In order to simulate transient phenomena in transformers, a system of equations is presented. The digital simulation of the energization and de-energization of a three-phase distribution transformer is studied ...

Modelling of a voltage transformer for transients

2005 IEEE Russia Power Tech, 2005
This paper presents the modelling of a 110 kV inductive voltage transformer for transients. The inductive voltage transformer ratio typically changes a lot for frequencies up to the 50th harmonic. To make a good model in this frequency range is the main task of this paper. A traditional lumped, linear model that includes capacitances gives satisfactory

Transients and the Laplace Transform

1991
In a circuit which contains one or more energy storage element, a transient state will exist whenever the energy condition in the circuit changes, until the new steady state is reached. This may be caused by changing the applied voltage or current, or by changing any of the circuit elements, usually by opening or closing switches.

Transient voltages in rectifier transformers

Transactions of the American Institute of Electrical Engineers, Part II: Applications and Industry, 1959
This paper discusses transient-voltage phenomena which occur in rectifier circuits involving mercury-vapor hot-cathode tubes commonly used as power sources in many electronic equipments such as broadcast transmitters, high-frequency industrial-heating applications and the like.

Transient Temperature Rise of Transformers

Transactions of the American Institute of Electrical Engineers. Part III: Power Apparatus and Systems, 1962
Equations are developed for transient temperature rise of transformer cooling medium and various types of transformer coils over their ambient medium. These are evaluated on a percent temperature rise base for the corresponding powers of the watts dissipated for transformer cooling medium and various types of transformer coils.
