A current transformer reset circuit, which uses two separately controlled operational parts to reset a current transformer. The first operational part is a current source used to generate a reset current. The second operational part is a reset switch, which when turned on allows reset current to ...
PURPOSE: To obtain a current-transformer circuit which increases the reliability of an apparatus by a method wherein positive DC power supplies and negative DC power supplies are installed at a plurality of current transformers and the current conduction polarity of a current- transformer primary curr...
PURPOSE: To change promptly and easily a current transformer even after a breaker is assembled by installing a prompt exchange assembly of a current transformer built in the breaker. CONSTITUTION: A current transformer 54 perceives a state of the overcurrent, and trips a breaker 20 sending a si...

WARNING: Do not use automatic reset mode in applications where unexpected automatic restart of the motor can cause injury to persons or damage to equipment.WARNING: The improper selection of a current transformer can result in the overload relay not properly protecting the motor and possible motor ...
发明人: U Riyouhei 摘要: PURPOSE:To provide a current detection output, with almost no ripple, from a single DC power source, by such means that using two current transformers, alternately through a switch method, a reset be operated with the DC power source.收藏...
The protection circuitry for each phase (L1, L2, L3) has a current transformer (CT1, CT2, CT3), each current transformer (CT1, CT2, CT3) having a primary side which is connected to the phase (L1, L2, L3), and a secondary side. A fuse (FA, FB, FC) is connected to two ...
Resonance circuit with transformer - has transformer with prim. and sec. coils, control voltage source connected to prim. coil, single switch device for on... The resonance capacitor (16) works in conjunction with the prim. coil (2) to produce a series resonance and a voltage impulse, when...
A residual current circuit breaker (RCCB) is an electrical safety device that detects and interrupts an electrical circuit when there is a leakage current to the ground. It protects people and equipment from electric shocks, fires, and other hazards caus
This is because the rate of energy transfer to a circuit cannot be infinity. So the flux in the core also will start from its zero value at the time of switching on the transformer. According toFaraday’s law of electromagnetic inductionthe voltage induced across the winding is given as e...
