Latest news from Megger
New high current micro-ohmmeter works your way
Megger’s new DLRO100 digital low resistance ohmmeters are readily portable lightweight instruments that can deliver a test current of 100 A. They can be supplied with internal rechargeable Li-ion batteries that provide sufficient power for up to 200 manual/automatic tests on a single charge. This makes it easy for users to perform high-current low-resistance testing in almost any location, even if there is no access to a mains supply.
New Megger bridge finds HV cable faults quickly and accurately
Robust, readily portable and easy to use, the HVB10 high-voltage bridge from Megger allows cable and sheath faults in power cables to be prelocated reliably and accurately, even in difficult applications. The instrument, which also has facilities for sheath fault testing and sheath fault pinpointing, is particularly suitable for use on long HV cables, and in situations where pulse-reflection methods of fault prelocation do not give satisfactory results.
Ohmmeter tests transformers faster and safer
With the capability of testing two windings simultaneously, Megger’s new MTO250 transformer ohmmeters reduce the time needed for testing by up to 50% compared with conventional instruments, making them an ideal choice for field and factory testing of current transformers, potential transformers and power transformer windings. The new testers also incorporate a comprehensive range of safety features to protect the user and the asset under test.
There's a new MFT on the block!
In response to the fast changing needs of today’s electrical contractors, Megger has launched the new MFT range of multifunction installation testers. These combine the highest levels of safety with ease of use, exceptional versatility and outstanding value for money. All models in the new range have valuable extra functions that have been carefully selected to make life easier and more convenient for users.
Cut the cost of eliminating battery failure
By offering a convenient and reliable way of monitoring the voltage of individual cells during storage battery discharge testing, the new BVM battery monitor from Megger allows failing cells to be readily located. This means that battery performance and reliability can be restored by simply replacing the defective cells, rather than the much more costly option of replacing the whole battery.
Safely check for live circuits with Megger's new two-pole tester
Compact, convenient and versatile, Megger’s new TPT320 two-pole tester provides electrical contractors with a safe and reliable way of checking AC and DC voltages from 12 V to 690 V. Designed from the outset with safety in mind, the new tester not only has a CAT IV 600 V safety rating in line with EN 61010-1:2010, it also complies fully with the recently introduced EN 61243-3:2010 standard that specifically covers the safety of two-pole voltage testers.
SMRT36 - the smart solution for relay testing
The SMRT36 is a smaller and lighter protective relay test set, and has more output power than any other comparable three-phase instrument available anywhere. The SMRT36 has a unique constant power output, produces a compliance voltage of 50 V at up to 4 A (200 VArms), and maintains 200 VA output power up to 30 A, making it ideally suited for testing in today's installations and legacy plants. Also, with its forward thinking design, the SMRT36 is positioned for future challenges associated with smart grid testing.
Test diagnostics for HV cables in a single system
To maximise both user convenience and value for money, Megger’s new HV DAC300 test set combines withstand testing facilities and partial discharge diagnostics for HV cables operating at up to 230 kV in a single readily transportable system. The DAC300 uses damped AC (DAC) voltage technology to energise the cable and is capable of generating peak voltages of up to 300 kV. It can be used with cable with capacities of up to 8 µF.
The ultimate testbox for substations
Portable test equipment expert, Megger, has launched a new protection relay and substation test system that combines exceptional versatility with rugged reliable construction, portability and ease of use. In a single compact unit, the new SVERKER900 provides engineers with a comprehensive range of tools that cover all major requirements for single and three-phase testing in distribution substations, renewable power generation installations and industrial applications.
