The PD Profiler™ is a cutting-edge Partial Discharge Monitor designed to boost reliability and safety of electrical systems. With its flexibility, the PD Profiler™ enables electrical maintenance professionals to conduct on-site partial discharge surveys or seamlessly integrate the device into permanent monitoring systems for comprehensive grid coverage.
- Best For: On-site partial discharge surveys, permanent monitoring systems and larger HV networks requiring multi-channel PD visibility.
- Detection Capability: Supports 8 to 20 PD channels with PRPD diagnostics, helping teams identify, trend and interpret partial discharge activity across multiple assets or measurement points.
- Installation Options: Can be used as a standalone monitoring device or integrated into onsite monitoring systems, with scalable daisy-chain deployment and no shutdown required for installation.
- Key Benefits: Provides easy-to-understand trend analysis, advanced interference management, onboard memory for several months of recordings and flexible deployment for both survey work and long-term grid coverage.
Next generation sensor capability and the primary sensing device on the PDProfiler system. Using combination of TEV and US sensing. This one model supports internal and external installation and can be changed over its lifetime with minimal effort.
- Best For: HV & Cabinet PD detection
- Detection methods: US, TEV/Acoustic
- Installation options: Perfect for Installation live, can be housed internally during shutdown window using same sensor. Advanced combination sensor reduces impact and re-engineering.
- Key benefits: PD Diagnostics, Non-Intrusive detection, Flexible placement, Higher powered sensor.
High Frequency Current Transformers, HFCT-20HD & HFCT-60HD™, are used as a secondary PD measurement point and are designed for partial discharge detection on assets main earth bonding
- Best For: Cable earths, busbars, GIS grounding conductors and secondary PD measurement.
- Detection methods: High-frequency current detection.
- Available Sizes: 20mm and 60mm apertures.
- Key benefits: Split-core design, noise shielding, rugged housing, weatherproof IP66 and liquid-resistant design.
Monitoring Platform, allowing remote access and alarm management from PD Annunciator™ modules.
- Best For: Remote monitoring & alarm management, expert analysis, SCADA/BMS integration or local alarming.
- Connectivity Options: Cloud or monitor locally via Modbus data connection, connect with SCADA//BMS/PM, cloud platform and condition-based maintenance integration.
- Key Benefits: Supports safe remote visibility, alert management, trend analysis, expert monitoring and removes the need for routine PD handheld measurements that put operatives in potentially dangerous environments
Hire a Portable Online PD Monitoring Kit
Continuous PD visibility without a permanent installation.
ACTENIQ can deploy a portable online PD monitoring system on a monthly hire basis, giving teams a quicker, lower-disruption way to monitor suspected PD risk without installing a permanent fixed solution.
This is ideal for urgent concerns, short-term risk assessment, planned shutdown decisions or assets that need to be monitored safely from a distance.
A complete ndb monitoring solution, not just the hardware
ACTENIQ does more than provide ndb partial discharge monitoring equipment.
We help organisations select the right monitoring approach, design the system around the asset, manage installation and ensure the data can be used properly by engineering, facilities and operational teams.
From portable online monitoring for suspected PD activity to permanent systems across critical HV infrastructure, we support each stage of the project – including system design, installation, commissioning, training, remote monitoring, expert analysis and ongoing support.
Where PD activity is identified, we can help interpret the findings and support the next step, from further investigation and planned inspection to remedial works, asset replacement planning or long-term condition monitoring.
Frequently Asked Questions
Who are ndb Technologies?
ndb Technologies are a Canadian OEM with global coverage, specialising in the development, manufacture and marketing of portable and fixed high-technology test and measurement equipment for the electrical utility and private HV market. You can find more about them here
Can I buy ndb partial discharge monitoring equipment directly from ndb Technologies?
No. For the UK and Ireland, ACTENIQ is the exclusive partner for ndb Technologies’ online partial discharge monitoring systems. This means that customers based in the UK and Ireland customers should speak to ACTENIQ for ndb product advice, system design, supply, installation, commissioning, training and ongoing support.
How long does it take to install?
Installation time depends on the chosen system, site access, asset type and whether the deployment is portable, semi-permanent or permanent. Some systems can be deployed quickly for urgent PD visibility, while larger multi-asset installations may take longer to design, install and commission. ACTENIQ can confirm expected installation times once your site and monitoring requirements have been reviewed.
How much does an ndb partial discharge monitoring system cost to install?
The cost depends on the monitoring approach required, the number of assets being monitored, the sensor configuration, connectivity requirements and whether the system is portable, semi-permanent or permanently installed. ACTENIQ can review your site requirements and recommend the most suitable ndb monitoring setup based on your risk, infrastructure and budget.
Can the system be installed without a shutdown?
In many cases, externally mounted sensors and portable monitoring options can be installed without a power outage, depending on the asset type, access and site requirements
Do you hire out temporary portable partial discharge monitoring systems?
Yes. We can provide temporary portable online PD monitoring systems on a monthly hire basis. This is a useful option for sites that need quicker visibility without committing to a permanent fixed system straight away.
Unlike a handheld survey, which only captures partial discharge activity at the exact moment the test is taken, a portable online system can monitor continuously over time. This helps teams confirm suspected PD activity, track developing trends, receive alerts if conditions deteriorate and monitor potentially dangerous assets remotely.
Portable monitoring is ideal for urgent PD concerns, short-term risk assessment, planned maintenance decisions or sites that need a faster, lower-disruption way to understand what is happening across critical HV assets. Call us on 0333 880 2848 to get more details
Can ACTENIQ help interpret PD data?
The ndb system supports clearer interpretation by using multi-level averaging, noise floor adjustment, smart alarming and trend analysis to help separate one-off spikes from genuine developing PD activity.
But if you need additional assistance, ACTENIQ can support expert analysis, trend review, alarm management and practical recommendations around inspection, maintenance and remediation.
Can ACTENIQ help after partial discharge is detected?
Yes. ACTENIQ can interpret the data, assess risk, recommend next steps and support remediation planning or ongoing monitoring.
Need ndb partial discharge monitoring at your site?
The first step is to give us a call or submit an enquiry form. From suspected PD activity to long-term HV asset visibility, tell us what you need to monitor and we’ll help identify the right product, deployment and support model for your site.
