Full title and description

IEEE Recommended Practice for Partial Discharge Measurements under AC Voltage with VHF/UHF Sensors during Routine Tests on Factory and Pre‑Molded Joints of HVDC Extruded Cable Systems up to 800 kV. This recommended practice defines a protocol for carrying out partial discharge (PD) measurements using AC voltage and VHF/UHF electromagnetic sensors as a quality‑control method for factory and pre‑molded joints of HVDC extruded cable systems (rated up to 800 kV). It covers sensor checks, test setup preparation, measurement procedure and success criteria with the objective of detecting critical PD activity within the insulation of the tested joint (excluding external discharges such as corona from electrodes or leads).

Abstract

This document provides recommended procedures for routine PD testing of factory and pre‑molded joints in HVDC extruded cables using AC voltage and VHF/UHF sensors. It emphasizes a protocol-driven approach (sensor performance check, test arrangement, signal interpretation and pass/fail criteria) intended to identify whether critical partial discharge activity exists within the tested object rather than to enforce a fixed amplitude threshold. The practice is targeted at systems with rated voltages up to 800 kV.

Scope

This recommended practice establishes a standardized protocol for partial discharge measurements performed with AC voltage and VHF/UHF electromagnetic sensors during routine production and factory testing of factory‑assembled and pre‑molded joints in HVDC extruded cable systems rated up to 800 kV. The scope explicitly excludes assessment of external discharges (for example corona from high‑voltage electrodes or conducting test leads) and focuses on identifying PD originating within the insulation of the joint under test. The practice describes sensor performance checks, test setup requirements, measurement steps and criteria to assess whether critical PD is present.

Key topics and requirements

• Recommended measurement protocol for PD detection in factory and pre‑molded joints using AC voltage and VHF/UHF sensors.
• Sensor performance check procedures and verification steps prior to testing.
• Test‑setup preparation: electrode arrangement, grounding, cabling and noise mitigation.
• Signal processing and interpretation guidance to distinguish internal (critical) PD from external noise or corona.
• Success criteria and pass/fail considerations for routine quality‑control testing (focused on presence/absence of critical PD rather than fixed amplitude limits).
• References and alignment to related international guidance (examples cited in the standard: CIGRÉ technical brochures and IEC TS 60270).

Typical use and users

Intended users include cable manufacturers, joint and termination suppliers, factory test laboratories, HVDC project test teams, utility acceptance/test engineers, independent test service providers and researchers working on HVDC extruded cable quality assurance. The practice is used for factory acceptance tests, routine production quality control and pre‑shipment verification of joints and terminations to detect whether internal PD activity that could compromise long‑term performance is present.

Related standards

The standard references and aligns with other guidance and technical reports used in high‑voltage cable testing, including CIGRÉ technical brochures (for example TB 89 and TB 496 as noted in the document's referenced materials) and IEC TS 60270 (partial discharge measurement techniques). Within IEEE activities, related recommended practices for HVDC cable testing (for example IEEE 1732 series on space charge measurements for HVDC cable systems) are relevant for broader HVDC test programs.

FAQ

Q: What is this standard?

A: IEEE Std 2862‑2020 is a recommended practice that defines procedures for measuring partial discharges with AC voltage using VHF/UHF sensors on factory and pre‑molded joints of HVDC extruded cable systems up to 800 kV.

Q: What does it cover?

A: It covers the full measurement protocol for routine PD testing: sensor checks and verification, recommended test setup and arrangements, guidance on signal interpretation to distinguish internal PD from external noise/corona, and success criteria to determine whether critical PD is present in the tested joint. The practice emphasizes detection of the phenomenon rather than specifying a single amplitude acceptance threshold.

Q: Who typically uses it?

A: Cable manufacturers, HVDC project test teams, utilities, factory and independent test laboratories, and engineers responsible for acceptance and quality control of HVDC extruded cable joints.

Q: Is it current or superseded?

A: As published and listed by IEEE Standards Association, IEEE Std 2862‑2020 is an active (current) recommended practice; it was published March 8, 2021 (approved in 2020) and remains within its active lifecycle unless formally revised or superseded by a later IEEE action.

Q: Is it part of a series?

A: It sits within the IEEE Dielectrics and Electrical Insulation Society (DEI/SC) portfolio addressing HVDC cable testing and assessment. It is complementary to other HVDC/extruded cable guidance (for example IEEE practices and recommended practices addressing space‑charge, type and qualification testing) and references international technical reports such as relevant CIGRÉ TBs and IEC TS 60270.
