The HVEX Portable Partial Discharge Meter is the ideal solution for insulation testing and diagnosis in high-voltage electrical equipment, enabling early fault detection and condition assessment of assets such as transformers, bushings, cables, motors, generators, circuit breakers, reactors and capacitors. With a portable configuration and automated operation, it delivers reliable measurements, detailed signal analysis and support for predictive maintenance in the field and in the laboratory.
The system is operated from an integrated case housing an industrial computer and dedicated software that acquire, filter and interpret partial discharge signals. It supports different sensors - external coupling capacitor, HFCT and capacitive tap coupler - allowing measurements across a wide range of applications. The system also includes a pulse calibrator and advanced analysis features, including AI-based self-diagnosis.

Typical applications:

Testing and monitoring of power and instrument transformers
Measurements on condenser bushings and wall bushings
Diagnosis of motors and generators
Testing of cables, terminations, joints and splices
Inspection of circuit breakers, reactors, capacitors, insulators and disconnect switches
Assessment of electrical assets in predictive maintenance and field inspections.

Sensors and acquisition:

External coupling capacitor: capacitive / resistive-capacitive divider for controlled signal pick-up on bushings and test points.
Split-core HFCT: high-frequency reading via the earth path, suited to cables, transformers and points without an accessible tap.
Capacitive tap coupler: adapter for condenser bushings acting as a capacitive divider and high-pass filter.
Sampling rate: 500 MSa/s; vertical resolution: 12 bits; usable frequency range: 10 kHz to 100 MHz.

PDMS software:

Full test control, digital filtering, graphical views and a database for measurement history.
Report export in PDF and DOCX, and compatibility with external signal-processing tools.
Intuitive interface with test parameter settings and automatic recording of results.

Applicable standards:
IEEE Std C57.124
IEEE Std C57.113
IEEE Std 1434
IEC 60270
IEC 60060
IEEE Std 400
ABNT NBR 5356

Built around an industrial computer and PDMS software in a single transport case, the HVEX Portable Partial Discharge Meter brings laboratory-grade PD measurement to the field. It combines high-speed acquisition (500 MSa/s, 12 bits, 10 kHz to 100 MHz), three interchangeable sensor types and an integrated pulse calibrator, so that charge measurements remain traceable and repeatable on transformers, bushings, cables, rotating machines, circuit breakers, reactors and capacitors.

Portable partial discharge measurement technology

introduction

Portable case-mounted system with an integrated industrial computer and PDMS software for control, analysis and report export.
Artificial-intelligence self-diagnosis that interprets PRPD maps (PRPD / Lissajous plots) and provides a technical rating of the asset condition.
Compatibility with three sensor types (external coupling capacitor, split-core HFCT and capacitive tap coupler), allowing measurements on a wide range of equipment and access points.
Integrated pulse calibrator (5 pF to 1000 pF) to ensure traceability and accurate test set-up in accordance with IEC 60270 / ABNT NBR IEC 60270.
A set of digital filters (high-pass, band-pass, low-pass) and views (sine, PRPD/Lissajous, FFT) for accurate analysis in noisy environments.
Non-intrusive operation, with quick installation and low operational impact.

HVEX Partial Discharges Calibrator is portable equipment that allows calibration with bipolar pulses at different intensities and frequencies, and can therefore be applied to partial discharge measuring instruments in oil or dry insulated transformers, generators, motors, bushings, cables, etc.

Partial Discharges Calibrator

The HVEX Monitoring System connects transformers to smart grids, sending real-time data such as voltage, current, and overload. It allows for the analysis of asset lifespan, detection of losses, and optimization of grid operation, as well as enabling energy balancing and time-of-use billing.
