Options incorporate testing equally ground resistance of tower legs (separately and total) and overhead ground wires. Measures leakage present throughout the tower legs. Tests at frequencies as much as 5kHz to profile impedance.
Merchants nearly ten Major/secondary nameplate voltages to utilize in comparing test results Displays ratio, test recent, winding polarity, and deviation from nameplate voltage or ratio
Along with our solution offerings AEMC® provides accredited one-working day and multi-day educational programs in ground resistance testing and electric power high quality Examination.
We produced the following all-in-just one, a person page comparison files to assist you pick out the most beneficial Megohmmeter to your precise needs.
The Ground Resistance Tester Product 6418 measures ground rod, busbar, and grid resistance and impedance without the usage of auxiliary rods. Clamp-on ground resistance testers can be utilized in multi-grounded techniques with out disconnecting or de-energizing the ground method beneath test.
The challenge: Because of their measurement plus the elements from which they’re created, windmills are remarkably liable to lightning strikes. Lightning is, in truth, the top reason behind downtime and catastrophic problems can take place if there’s not a good path from blade suggestions to the ground.
This video clip goes over the digital transformer ratiometer's features and performance. On top of that, when linked to a non-energized transformer, this instrument accurately measures Main to secondary turns ratio, though simultaneously exhibiting polarity and excitation present.
Steps insulation resistance from 1kΩ to 4000MΩ using a few consumer selectable test voltages of 250V, 500V, and 1000V. Can conduct continual tests around 15 minutes.
Easy Statements Procedure: File a claim anytime online or by mobile phone. Most statements authorized within just minutes. If we can easily’t fix it, we’ll ship you an Amazon e-gift card for the purchase cost of your protected products or replace it.
The answer: We advised the Megger DLRO10HD ohmmeter which provides 25W of ability which often can provide the required 1A test recent around the massive distances required by this software and which can Olympus Panametrics Epoch 600 Ultrasonic Flaw Detector test in accordance with IEC61400-24 requirements for small-resistance ohmmeters.
