How Much Current is Enough?

Measuring low resistance – which is usually taken to mean resistance of less than 1Ω – has many applications, from checking the condition of circuit breaker contacts to verifying the integrity of welds in metal structures. One very common question however is, “What’s the best test current to use?” As is usual with questions like this, there is no simple “one size fits all” answer.

Breaker Failure Testing

When a breaker fails to open contacts or interrupt current after receiving a tripping signal from a primary relay, we have a breaker failure. Most protection systems have a breaker-failure scheme and it is important to test this backup protection as part of your regular relay testing program.

Locating Battery Ground Faults

Ground faults often develop in substation battery systems over time due to environmental factors and maintenance activities. Dirt and debris accumulated on battery surfaces can create electrical paths to the battery rack. Electrolyte residue due to cracking or crazing of the battery container also results in conduction paths to the battery rack. This application note will cover how to use the Megger BGL to trace and locate ground faults on a live DC system, without sectionalizing any circuits.

Cable Insulation Resistance Testing

Insulation is used in cables to protect the conductor and to ensure that there is no connection between the two current carrying components of the cable – the conductor and the metal screen. Three commonly used dielectrics for High and Extra-High Voltage cables are impregnated multi-layered paper, oil filled paper and extruded polymer. A simple insulation resistance test is the easiest and fastest way to determine the insulation condition of both new and old cables.

Megger brand

Our strategy is to produce all our products with a single brand name, Megger. The advantages to you are that you know the products and software will work well together, and all the products have a similar yet distinctive 'look and feel' with their dark and light grey casings. We don't waste colour on trying to make our test instruments pretty – we reserve it for useful functions such as range selectors and displays. Our design engineers come from many different nations, and they regularly exchange ideas and tips with colleagues from other countries. That means you get the latest innovations, one of the reasons that Megger products are so advanced. As more companies join the Megger family, you may find some test equipment sold by us that have not yet transitioned to the Megger identity system. Don’t worry – our top priority is ensuring that product quality is right. We’ll get round to making sure the colours are the same later.

How the greatest brands in test and measurement came together

Our systems are geared to keeping things local – localised engineering, localised marketing, localised decision-making. Our employees are proud of the companies and brands that go to make our company history and many of these names are still trademarks or registered trademarks of the company in many countries.
