The ground resistance of substations can be measured with two auxiliary electrodes which are put into the ground. To avoid influences from the mains current and its harmonics, this measurement should preferably be carried out with 128 Hz.The high output power of the CPC 100 ensures a high ratio of the signal level to the noise level. Thanks to the signal processor technology, the measuring procedure is very selective and disturbances by ground currents are reduced to a minimum.

3731 Clamp-On Ground Resistance Testers
The Clamp-on Ground Resistance Tester Model 3731 measures ground rod and small grid resistance through any season, without the use of auxiliary ground rods.
Check Resistance on Single and Multiple Rods or Grids
Clamp-on Ground Resistance Testers are used in multi-grounded systems without disconnecting the ground under test. The Model 3731 simply clamps around the ground conductor or rod and measures the resistance to ground. By performing measurements on intact ground systems, the user also verifies the quality of the grounding connections and bonds. Resistance and continuity of grounding loops around pads and buildings may also be measured.
The Model 3731 also provides alarm and memory functions.

Ground resistance meter 3-electrode measurement on the 3151 gives greater precision !
Ground resistance measurement involves factors that are not encountered during ordinary resistance measurement, such as polarization of the earth, the influence of grounding current due to leak current and grounding voltage, and the influence of auxiliary grounding resistance. The 3151 is able to make more accurate measurements more safely under difficult conditions because it uses the alternating current potentiometer method to provide measurement accuracy, and because it contains features such as an auxiliary grounding resistance check feature and measurement frequency switching.

Testing of insulation plays a great role in electrotechnics.Dielectric breakdown tests are important to the safe functioning of everything from power distribution transformers to household appliances. Impulse voltage tests are characterized by a 1.2/50us waveform. This is as industry standard.
The huge range of devices to be tested requires impulse generators from a few hundred volts(V) up to hundreds of thousands of volts(kV). The impulses have low energy content, but this can vary depending on the application.
EMC PARTNER offer a range of instruments starting from 250V up to 100kV. All units have the necessary connections and safety features relative to the test.
Many product specific standards incorporate insulation testing as part of the safety criteria.

The S1-552 is an advanced 5kV insulation tester with a high output current and many time-saving features. A large, analog/digital LCD shows resistance valves up to 5 T%u03A9 and incorporated a timer and other test information. The output current, of up to 5mA, speeds up testing by charging capacitive loads quickly.
The 5 and 15-kV Megohmmeters are high-voltage, line operated instruments that can be used on all types of insulation tests ranging from 500 volts to 15 kV.
With over twenty 1-kV models to choose from, selecting the proper Megger insulation tester can appear a bewildering task at first. Actually all the process requires is a little organization. All Megger insulation testers perform essentially the same test in fundamentally the same manner %u2014 accurately and reliably. Refinements and added features, however, separate one model from another in application and operator appeal.
