Types of voltage and current source: Empower your designs
Voltage Source and Current Source The voltage compliance range of current sources is one of their key concepts. This implies that only a specific field of output voltages will allow a current source’s output to be accurately measured. Typical current source circuits typically have a high-side PNP transistor as the primary control element. Ideal circuit...Read More
Difference Between AC Hipot Test and DC Hipot Test
High Point represents high potential and is a term used for a specific class of test equipment for electrical insulation. Hipot testers are the reverse of the continuity tester- it conducts the discontinuity test checking no current flow condition between two points. Hipot tests are conducted to find crushed, or leakage in the insulation, and...Read More
Types of Losses in a Transformer and Their Effectiveness
An ideal transformer is a transformer that doesn’t have any energy losses. This means that the power supplied to the transformer’s input terminal should be equivalent to that provided to the transformer’s output terminal. Hence an ideal transformer has equal input and output power combined with zero energy losses. When a transformer ratio meter is...Read More
Difference between Single-Phase and Three-Phase Transformer?
The transformer is an electrical device that transfers electrical energy between two or more circuits through inductively coupled conductors in the transformer’s coils. It can be a single-phase transformer or a three-phase transformer. There are many differences between auto variable transformer manufacturers that you need to know about. Here is some basic information about single-phase and three-phase...Read More
Instructions for use and safety measures for hipot testing
Hipot testing has long been a common practice verifying that electronic equipment complies with electrical safety standards. Early commercial hipot testers essentially consisted of a variac-driven step-up transformer to ramp up the test voltage. Then dwell at the designated voltage for the set amount of time while keeping an eye out for excessive leakage current or device...Read More
The importance of high voltage equipment testing & repair:
You probably had a toy as a kid that doubled as a scientific experiment showing how electricity works. Of course, it was enjoyable. Even as grownups who are aware of its potential uses and what you already know you are capable of, electricity is still entertaining. High voltage testing equipment is an imperative necessity to...Read More
5 Things You Need to Know About Low Resistance Testing
Low resistance in the electrical testing industry refers to resistance values below 1 ohm. If this is a new concept, you may think 1 ohm is already low. But remember that it can go lower. It would be best to use an instrument with an extremely high resistance meter and a high enough test current...Read More
What are the Effects of High Voltage Transmission Lines on Humans and Plants?
As the world’s population grows, towns are getting bigger, and many new buildings are going up near high voltage power lines. Because people use more power, they must expend vast energy over long distances. Large configurations of transmission lines with high levels of voltage and current create strong electric and magnetic fields that affect people and things...Read More
Navigate Electrical Troubleshooting For Your Facility
When a technician fixes a complicated piece of equipment, it gives them immense satisfaction. Having a good plan for resolving problems and following them can help you feel this way. Here is a troubleshooting process to help you determine what is wrong with your facility’s electricity using hi-pot testing equipment. Gather Information The first step in...Read More
Pre-Testing Arrangements for Hipot Testing
The electric grid network is often referred to as critical infrastructure. For electric utilities, any interruption that causes a lot of downtimes is a significant source of revenue loss. As a result, policymakers expect network operators to deliver electricity to retail customers around the clock. As a result, hi-pot testing equipment must meet the highest standards of...Read More
