Latest news from Megger

Capable of providing accurate measurements up to 10 TΩ for 5 kV versions and 20 TΩ for 10 kV versions and having facilities for IR, IR(t), PI, DAR, DD, SV and ramp tests, Megger's new high-voltage insulation resistance testers (IRTs) offer exceptional versatility in a compact, rugged and light unit that weighs little more than half as much as its predecessors.

While capable of delivering 900 A continuously and 5,000 A for short periods, the new Ingvar primary current injection test set from Megger is readily portable, making it ideal for on-site use, even in applications such as underground substations where access would be difficult or impossible for larger test sets. The design has also been optimised to minimise in-rush current, thereby making Ingvar suitable for use on supply systems with limited capacity

With the launch of the new TM1700 range of circuit breaker analysers from Megger, users with regular circuit breaker testing requirements no longer have to choose between low-end instruments designed only for simple applications and versatile but costly high-end instruments.

Developed specifically to make installation testing safer, faster and more convenient, Megger's new and innovative MFT1700 series instruments set new standards for multifunction test sets.

Megger MTO300 series transformer ohmmeters measure all six windings of a three-phase transformer automatically without changing connections. With test current capability up to 10 A, they provide simultaneous winding magnetisation to ensure fast, accurate results, and auto-demagnetisation after test. And, by sharing the same lead set as Megger TTR turns ratio testers, they make transformer testing even more convenient.

In response to the growing recognition of the benefits of 15 kV DC insulation testing, Megger, a world leader in portable electrical test equipment, has introduced two new instruments with 15 kV testing capabilities – the MIT1525 and the S1-1568.

By using a user selectable test current from 80 A up to 1,000 A, the new Megger NIM1000 network impedance meter allows users to make accurate loop impedance and fault current measurements on live circuits, close to the source of supply, even in large electrical installations such as those found in major hospitals and on big industrial sites.

With the new PCA2 protection condition analyser from Megger, it is now possible to test simultaneously all of the key elements of substation protection systems - including protection relay, circuit breaker, DC system, and protection circuitry - even while the system is on-load. The unit captures detailed information about the full protection operation sequence, before, during and after the trip, making it an ideal choice for critical first-trip testing.

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.

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.
