VLF Insulation Testing
VLF testing uses very low frequencies as part of an AC cable maintenance routine. VLF testers are smaller and more practical than AC testers but output the same amount of power as a 50 Hz mains device. This combination of size and power makes Very Low Frequency cable testing perfect for testing longer sections of cable and apparatus

Cable Sheath Fault Location
Locating cable sheath faults is one of the last steps in cable testing, occurring after you have identified the existence of a cable fault via the identification procedure based on your specific site variables and the type of system you are working on

AC Insulation Testing
AC insulation tests are a popular response to the increasingly demanding industrial, power and domestic marketplaces. Insulation materials have had to become more efficient to keep up with demand; more efficient equipment requires less insulation material to meet the minimum acceptable value of insulation resistance. In turn, cables have become smaller and lighter. However, under certain higher stress testing conditions such as DC testing, cables like Crossed Linked Polyethylene (XLPE) can quickly degrade.

DC Overvoltage or Withstand Testing
Overvoltage protection is critical to the long-term health of any cable. DC overvoltage testing (also known as withstand testing) is the most popular method of general condition and integrity assessment in the power, industrial and domestic markets. This method of testing is distinguished a number of key advantages:

Low Resistance Ohmmeters
Some times know as Ducter testers, these are highly accurate, easy to operate instruments that measure resistance with resolution as fine as 0.1 micro-ohm. Digital micro-ohmeters and DLROs measure contact resistance of switch and circuit breakers, aircraft frame bonds, and rail and pipeline bonds just to name a few of the applications. Megger has models available for testing using test currents from 0.5 mA to 200 amps covering a multitude of applications that require precise low-resistance measurements.

Ground Testing
Ensuring an effective earth system is essential in a telecommunications system, and Megger is expert in earth testing having been there right from the start. These days Megger offers top end systems for design and soil surveys as well as tough easy to use testers for field engineers. We have tried to make the testers self checking as much as we can, to allow you to concentrate on collating and understanding the results.

Cable Fault and Test System Vans
Whether you are working on-site, in the countryside or an urban environment, having the right equipment available when conducting fault location operations is vital. When the correct tools can be accessed easily, fault-location time speeds up dramatically, and faults can be dealt with more efficiently. Megger’s range of cable test vans offer solutions to the challenges of fault location in the real world, no matter the environment. Our test van systems have been developed in collaboration with end users to ensure that they live up to the standards of daily fieldwork. Our vans are designed to be adaptable to the end users needs so that the most appropriate tests may be carried out for the cable in question, regardless of whether it is low, medium or high voltage.

Contact Resistance Test Sets
When a high current passes through a pair of mechanically independent metallic contacts, the resistance must be as low as possible. An increase in resistance can lead to additional degradation, as I2R losses will cause local heating of the contact surfaces. Our range of micro-ohmmeters measure both steady state and dynamic low resistance values. With test currents up to 600A available, logging and trending are also available on some models. We ensure that our Contact Resistance tests sets are portable, making them suitable for field measurements. Our contact resistance testers’ portability makes them ideal for a vast range of resistance testing across the entire LV, MV HV and EHV spectrum.
