Earth resistance clamp testers for large round and flat conductors

  Clamps with elliptical apertures that can accommodate cables up to 39 mm diameter and flat earth tapes up to 50 mm wide make Megger’s new DET14C and DET24C earth resistance clamp testers quick and easy to use, even with large conductors and in applications where access to conductors is restricted. In addition, these instruments […]

Digital earth tester for three-terminal measurement

  The Megger DET3TD digital earth tester is a compact instrument designed to measure earth electrode resistance. It uses the three-terminal method of measurement, in which the current circuit’s resistance does not affect the reading. The instrument circuit is designed so that the resistance of the potential circuit also does not affect the measurement. Pressing a […]

Power cable fault locator systems

  The PFL40A Series Cable Fault Locating System from Megger provides a safe, efficient and easy–to-use solution for quickly identifying and isolating faults over a wide variety of power distribution cables. Up to 2000 joules of constant energy output is achieved over multiple voltage ranges of 8, 16 and 34 kV. The PFL40A offers DC […]

Terminal blocks with surge protection

Dehn’s Dehnconnect SD2 surge arresters are designed as space-saving terminal blocks with a width of 6 mm. These terminal blocks with integrated surge protection have a modular disconnect function which allows the user to interrupt the signal circuit for maintenance work. An integrated module ejector disconnects the signal circuit from terminal equipment. The disconnection module […]

Surge arrester for universal use

Dehn’s Blitzductor XTU is surge arrester for instrumentation and automation systems that adapts itself to the nominal voltage of the installation. The combined lightning current and surge arrester can be used for all voltages from 0 to 180 V DC.  Moreover, it continuously adapts its voltage protection level to the currently applied signal voltage and is […]

Testing substation protection systems

With the new PCA2 protection condition analyser from Megger, it is now possible to test simultaneously all key elements of substation protection systems including the protection relay, circuit breaker, DC system, and protection circuitry. The unit captures detailed information about the full protection operation sequence, before, during and after the trip, making it an ideal […]

Insulation resistance tester for diagnostic testing

The Megger MIT1025 insulation resistance tester is an advanced 10 kV test set for the diagnostic testing and maintenance of high voltage electrical equipment. In addition to measuring insulation resistance to 20 TΩ, the MIT 1025 also offers polarisation index, dielectric absorption ratio, step voltage, dielectric discharge and ramp testing. The tester has advanced memory […]

Overhead line overcurrent detector

The IKI-Overhead from Kries is used to detect over-currents, short circuits, earth faults and broken overhead lines in overhead distribution lines. Suitable for use on overhead lines with nominal voltages up to 36 kV, the device can be installed and removed directly on the energized line. In solidly earthed networks, and networks with NER/NEC systems, […]

Insulation tester with high noise immunity

All manufacturers of insulation testers claim that their products offer high noise immunity and, indeed, all test sets sold in the EU must meet the EMC requirements of IEC 61326-1. But experience has shown that in environments like substations and switchyards, the levels of electrical noise are often much higher than those laid down in […]
