What are isolation circuits?
Isolation is the electrical or magnetic separation between two circuits and often used to separate two distinct sections of a power supply. The isolation provides a barrier across which dangerous voltages cannot pass in the event of a fault or component failure.
How do you ensure a circuit has been safely isolated?
THE RULES OF SAFE ISOLATION ARE:
- Obtain permission to start work (a Permit may be required in some situations)
- Identify the source(s) of supply using an approved voltage indicator or test lamp.
- Prove that the approved voltage indicator or test lamp is functioning correctly.
- Isolate the supply(s)
- Secure the isolation.
What must be provided in the way of isolation electrical?
The basic rules, however, are that there should be isolation from the power source (usually, but not exclusively, electrical energy), the isolator should be locked in position (for example by a padlock), and a sign should be used to indicate that maintenance work is in progress.
What does isolation mean in a PCB design?
There are two types of power supplies that can be designed into a circuit board; isolated and non-isolated. Although isolation can refer to separating the power supply parts from the rest of the design on the PCB, it usually refers to isolation between the inputs and outputs of the power supply itself.
Do you have a proper procedure to isolate power?
Martindale Electric specialises in products to help electricians and maintenance engineers to prove dead and isolate power to prevent electric shock. Martindale recommend you to follow these easy steps to stay safe when working with electricity.
What does isolation mean in a power supply?
Although isolation can refer to separating the power supply parts from the rest of the design on the PCB, it usually refers to isolation between the inputs and outputs of the power supply itself.
What do you need to know about safe isolation?
When carrying out a safe isolation procedure on a three-phase circuit, there is a combination of ten tests that need to be carried out: Martindale have designed a poster that you can use to remind you of the steps to safe isolation. Download and display this to remind everyone of how to stay safe when working with electricity.
