VLF Sine 37 kV
High-power test and diagnostic system for MV cables
About the product
The VLF Sine 37 kV with integrated tan delta is a compact, durable, and highly portable test and diagnostic system designed for medium-voltage (MV) cable networks.
A powerful, comprehensive solution for MV cable test and diagnostics
Combining robust performance with practical mobility, the VLF Sine 37 stands out as the most powerful portable unit in its class, capable of testing up to 1.6 μF @ 26 kVRMS, making reliable testing and diagnostics of cables longer than 5 km effortless.
The unit is a truly multifunctional tool. It performs:
- VLF and DC testing
- Sheath testing and sheath fault pinpointing (with the ESG NT2 step voltage probe)
- Tan delta measurements for accurate assessment of cable condition and insulation integrity
- Can be used as a power source for partial discharge (PD) measurements to identify local problems such as workmanship issues
Thanks to its smart frequency control, the system automatically adjusts the test frequency based on cable length, ensuring testing even on 15 kV-rated cables up to 25 km long.

Megger TDR1000/3P
Handheld time domain reflectometer (TDR)
- Simple operation
- Auto setup for instant use
- Ultra fast pulse for near end fault identification
- Trace 'Hold' feature to allow comparison between cables
- IP54 rating offers real life working
- Designed for use on all metallic cable pairs
The TDR1000/3P handheld time domain reflectometer (TDR) is a compact, handheld instrument for locating faults on metallic cables. With built-in blocking filters and fused test leads, it has a minimum resolution of 0.1 m and a 5 km maximum range depending on the velocity factor selected and the cable type.
The TDR1000/3P has four output impedances available (25, 50, 75, and 100 Ω) and a four-way control switch that makes operating the instrument simple and inutive. It also has a velocity factor between 0.2 and 0.99, enabling it to meet any cable test requirements.
The instrument has an 'Auto selection' option that ensures that the most effective parameters are selected depending on the range required, aiding rapid diagnosis of the TDR trace. Dual cursors allow complete flexibility, giving you full control and an instant indication of the distance between two points. A trace 'Hold' feature also allows comparison between conditions, something not seen on most other handheld TDRs. Extra high resolution together with a white-light backlight and grey scale tones make the graphical display vibrant, helping you to identify key events on the trace.
PAT450
Portable Appliance Tester
Easy to use, light to carry, and featuring a convenient internal database for results storage, the PAT450 portable appliance tester is optimised for use by service organisations and equipment rental companies. Key benefits of the instrument include rapid start-up, instant restart after temporary disconnection when moving between test locations, and optional barcode support to aid in rapid asset identification.
- 10,000-record on-board memory
- Large 5.7 in. ¼ VGA backlit full color screen
- 200 mA; 10 A and 25 A bond test with high duty cycle
- Selectable PASS/FAIL limits
- Works with standard barcode scanners
These instruments offer both manual and automatic operation. When used in automatic mode, the test structure can readily be configured to suit specific requirements. This way, for example, a supervisor can predefine a test structure for a particular application and then be sure that all tests are performed exactly as required, irrespective of who carries out the testing work.
Contact Voltage Detectors
Contact voltage detectors are electronic devices that detect the presence of alternating voltage in electrical systems by making physical contact with the energized point, either in low, medium, or high voltage distribution networks, transmission lines, underground networks, substations, or industrial electrical installations.
Key Features
- High impact and dielectric strength polystyrene housing;
- For indoor and outdoor use.
- Powered by 9V battery;
- Automatic shutdown if battery charge drops below 7V;
- “STAND-BY” system – Ready for full-time measurement without using a battery;
- 80db sound signal at 1 meter distance.
Contact Voltage Detectors Datasheet
Megger ICMObserver
Partial Discharge Monitoring System
The ICMobserver combines the unmatched quality of the analogue front end of our current PD detectors with the additional features and benefits of the developments in digital signal processing during the last 20 years.
The ICMobserver is a versatile state-of-the-art monitoring system, which combines four devices in one solution: A spectrum analyser, a time domain oscilloscope, voltage measurement, and a PD monitor.
With the digital signal processing, the spectrum analyser offers a vast range of possible bandwidths. This greatly improves capabilities to deal with an elevated noise-floor that is inevitable in on-site monitoring conditions.
The built-in time domain oscilloscope together with fully parallel phase-resolved partial discharge patterns (PRPD) on all channels significantly expands the analysis options, so that you will be able to give an in-depth analysis of the condition of the monitored asset.
The modular concept of the hardware and software ensures expandability of the system for future applications, e.g., dissolved gas analysis (DGA) monitoring and temperature and load surveillance providing one data aggregation point.
- Versatile partial discharge (PD) monitoring system for medium and high voltage assets
- Fully parallel voltage and PD measurement on all channels
- Remote access and analysis options
- State-of-the-art digital signal processing for an immediate data display and in-depth analysis without the need for further equipment
- Partial discharge measurements according to IEC 60270
Fluke 931
Contact and Non-Contact Dual-Purpose Tachometers
The Fluke 931 tachometer is a handheld tachometer that integrates the contact and non-contact speed measurement functions and can accurately measure the revolutions per minute (RPM) or surface speed and distance. Fluke 930 is equivalent to a Fluke 931 with minimum configuration. With only the non-contact measuring function provided, it's more affordable and offers consistent quality.
Applications:
- Heavy manufacturing environments, e.g. automotive, textile, pulp and paper, metalwork
- Water purification plants
- Machining and chemical manufacturing plants
- HVAC compressors for industrial systems
Key features
- 6-digit backlight display reads the data clearly
- Signal detection reminder avoids invalid detection actions
- Maximum/minimum/average value and final readings
- Setting/Turning off the automatic power-off function
- Small size and easy to hold
- Easy switching of the contact and non-contact measurement modes
- Different speed measuring heads and rotational speeds adapt to different measurement occasions
