With the increased sophistication of electrical and electronic equipment, and new micro generation systems being added to the grid, there is now more than ever attention being paid to the quality of supply. Power quality surveys on electrical noise, lamp flicker, load balancing, power factor correction and motor in-rush studies can all be carried out with Megger power quality analysers.
One of the most important considerations in an electrical system is the resistance of the earth for reliable operation and safety. Whether you are doing a ground resistivity survey to plan the location of a substation or testing an earth electrode Megger has an earth tester suitable for the job. Megger has more than 50 years’ experience of designing and building earth resistance testers. The latest generation is CATIV rated, and have tough moulded cases. Variable test frequency keeps noise down, reliability up.
With the increasing dependency of back-up systems on battery strings, and the escalating cost of replacing batteries, instrumentation and software systems that can measure, trend and manage the life-cycle of cells is a cost effective option. There are two methodologies for testing batteries; the first, impedance testing is an on line test and can be performed
frequently to identify individual weak cells before they fail. The second, battery discharge test is, normally, an off-line test and tests the actual output of the whole battery under load conditions. This will show what will actually happen if the battery is required to take the load. Most battery systems are floating and have earth leakage monitors and trips if there is an earth fault. The Battery Ground Fault Tracer allows you to trace a faulty circuit easily in a complex floating system.
Baker Instruments’ motor test equipment are the industry-leading suite of products for detecting weaknesses and faults in the insulation systems of electric motors, generators and coils. Employing both low-voltage and high-voltage tests – such as Baker’s signature surge test – these essential troubleshooting and predictive maintenance tools allow maintenance professionals to assess any need to maintain or replace specific motors and generators that support their business. Equally at home in the motor repair shop or on a plant floor, these testers ensure that the electrical condition of your rotating machinery is understood.
Electrical contractors throughout the world depend on hand-held test equipment to ensure installations are safe and function correctly. Count on Megger to produce tough machines that are designed to surpass the requirements of wiring regulations.
