the term isolated refers to a certain section or even a whole circuit that is separated or de- energized from a power source. high voltage lines are often "isolated" by opening swiches or removing jumpers, usually when a section of line is isolated it is because of trouble, problems or dead work. if a circuit is loop fed rather then radial fed, you can isolate a section of damaged line and still keep many if not all customers hot. But don't be confused if a section of line is isolated that does not mean its dead because IF ITS NOT GROUNDED ITS NOT DEAD!
What else can I help you with?
Describe safe isolation procedure for safe systems of working in electrical circuit?
Shut it off and lock it out. Sign the lockout card and keep your key with you.
What term best describes an electrical circuit in which no current flows from the power source through the control component load and conductors?
A cold circuit
Does blu-tack break an electrical circuit?
No, an electrical approved switch is used to break an electrical circuit.
What constitutes a complete electrical circuit?
A complete electrical circuit occurs when it is possible for electrical current to flow through the electrical devices in it.
If an electrical circuit is not complete it is said to be?
An open circuit
What is the function of a build in an electric circuit?
I have never heard of an electrical term "build" in an electrical circuit.
What is the term used to designate the point in an electrical circuit where electrical work is done?
The term used to designate the point in an electrical circuit where electrical work is done is "load." The load is the component of the circuit that consumes electrical energy and converts it into another form of energy, such as light or heat.
What is the function of a double pole contactor in an electrical circuit?
A double pole contactor in an electrical circuit is used to control the flow of electricity to two separate circuits simultaneously. It allows for the isolation and switching of both the live and neutral wires in each circuit, providing a higher level of safety and control in the electrical system.
What is the difference between circuit protection and safe isolation in electrical terms?
Circuit protection refers to devices and systems designed to prevent overcurrent, short circuits, and overloads, thereby safeguarding electrical circuits and equipment from damage. Safe isolation, on the other hand, involves procedures and equipment that ensure electrical circuits are de-energized and cannot be inadvertently re-energized during maintenance or repair, protecting workers from electric shock. While both are essential for electrical safety, circuit protection focuses on preventing faults, whereas safe isolation focuses on ensuring safety during work on live circuits.
What term for the difference in electrical energy between 2 places in a circuit?
Voltage.
Describe safe isolation procedure for safe systems of working in electrical circuit?
Shut it off and lock it out. Sign the lockout card and keep your key with you.
What is the term for the relationship of voltage current and resistance in simple electrical circuit?
Ohms Law
What is the term for a complete electrical path?
The term for a complete electrical path is a circuit. It consists of a closed loop that allows current to flow from a power source to a load and then back to the power source. A circuit can include components such as wires, switches, resistors, and capacitors.
What term best describes an electrical circuit in which no current flows from the power source through the control component load and conductors?
A cold circuit
Which term describes electrical circuit with two or more devices connected to a source of electricity in one loop?
A parallel circuit
Why isolation is needed between power circuit and control circuit?
Isolation between power and control circuits is necessary to prevent high voltages or currents from affecting sensitive control components, ensuring safety and reliability of the control system. It also helps in preventing electromagnetic interference and noise from the power circuit, which could disrupt the control signals and lead to system malfunctions.
Can fuse isolate circuit?
Yes, a fuse can isolate a circuit by breaking the electrical connection when the current flowing through it exceeds a certain threshold. When the fuse blows, it creates an open circuit, preventing further current flow and protecting the circuit from damage. This isolation is a crucial safety feature in electrical systems, helping to prevent overheating and potential fires. However, unlike circuit breakers, fuses need to be replaced after they blow.
