  • Transformer Basics and Transformer Principles

    In an ideal transformer (ignoring any losses), the power available in the secondary winding will be the same as the power in the primary winding, they are constant wattage devices and do not change the power only the voltage to current ratio. Thus, in an ideal transformer the Power Ratio is equal to one (unity) as the voltage, V multiplied by

  • Residual-current device - Wikipedia

    A residual-current device (RCD), residual-current circuit breaker (RCCB), or ground-fault circuit interrupter (GFCI) is a device that quickly breaks an electrical circuit to prevent serious harm from an ongoing electric shock. Injury may still occur in some cases, for example if a human falls after receiving a shock, or if the person touches both conductors at the same time which an RCD wont

  • Current sensing - Wikipedia

    Two major sensing devices based on Faraday’s law are Current transformers (CTs) and Rogowski coils. These sensors provide an intrinsic electrical isolation between the current to be measured and the output signal, thus making these current sensing devices mandatory, where safety standards demand electrical isolation.

  • Transformer - The Reader Wiki, Reader View of Wikipedia

    A transformer is a passive electrical device that transfers electrical energy from one electrical circuit to another, or multiple circuits. A varying current in any one coil of the transformer produces a varying magnetic flux in the transformers core, which induces a varying electromotive force across any other coils wound around the same core.

  • Transformer - Simple English Wikipedia, the free encyclopedia

    Transformers are used to increase or decrease alternating current (AC) voltage in circuits. The transformer is usually built with two coils around the same core. The primary coil or input coil is connected to supply side while secondary coil supplies power to load. The second one is called the output coil.

  • Protective relay - Wikipedia

    In electrical engineering, a protective relay is a relay device designed to trip a circuit breaker when a fault is detected.: 4 The first protective relays were electromagnetic devices, relying on coils operating on moving parts to provide detection of abnormal operating conditions such as over-current, overvoltage, reverse power flow, over-frequency, and under-frequency.

  • Current limiting - Wikipedia

    An inrush current limiter is a device or group of devices used to limit inrush current. Passive resistive components such as resistors or negative temperature coefficient (NTC) thermistors are simple options, with power dissipation and cool-down time being their main drawbacks, respectively. More complex solutions using active components can be used when simpler options are unsuitable.
