High voltage tester standards for testing high voltage cables are essential to ensure the safety, reliability and longevity of power systems. These standards have been developed by various international and national organisations. The following are some of the key standards for high voltage cable testing:

1. International Standards (IEC)

• IEC 60502 – Power cables with extruded insulation and their accessories for rated voltages from 1 kV up to 30 kV.

• IEC 60840 – Power cables with extruded insulation and their accessories for rated voltages above 30 kV up to 150 kV.

• IEC 62067 – Power cables with extruded insulation and their accessories for rated voltages above 150 kV up to 500 kV.

• IEC 60229 – Tests on cable oversheaths with an extruded outer covering.

• IEC 60060 – High-voltage test techniques (defines test procedures for HV equipment).

• IEC 60885 – Electrical test methods for electric cables.

• IEC 61442 – Test methods for accessories for power cables with rated voltages from 6 kV up to 30 kV.

2. IEEE Standards (USA)

• IEEE 400 – Guide for Field Testing and Evaluation of the Insulation of Shielded Power Cable Systems.

• IEEE 400.1 – Guide for Partial Discharge Testing of Shielded Power Cable Systems in a Field Environment.

• IEEE 400.2 – Guide for Field Testing of Shielded Power Cable Systems Using Very Low Frequency (VLF).

• IEEE 400.4 – Guide for Field Testing of Laminated Dielectric, Shielded Power Cable Systems Rated 5 kV and Above with High Direct Current Voltage.

• IEEE 48 – Standard for Test Procedures and Requirements for Alternating-Current Cable Terminations.

• IEEE 404 – Standard for Extruded and Laminated Dielectric Shielded Cable Joints Rated 2.5 kV to 500 kV.

3. CENELEC (European) Standards

• EN 50395 – Test methods for low voltage energy cables.

• EN 50396 – Non-electrical test methods for low voltage energy cables.

• HD 620 / HD 621 – Harmonized standards for power cables with extruded insulation.

4. National Standards

• BS (British Standards)

• BS 6622 – Cables with extruded insulation for rated voltages from 3.6/6 kV up to 18/30 kV.

• BS 7835 – Cables with extruded insulation for rated voltages from 6.35/11 kV up to 19/33 kV.

• ANSI/NEMA (USA)

• ANSI/ICEA S-93-639 – Standard for Power Cables with Cross-Linked Polyethylene Insulation.

• DIN/VDE (Germany)

• DIN VDE 0276 – Power cables with extruded insulation.

5. Common High Voltage Cable Tests

• Type Tests (Design Verification)

• Partial Discharge (PD) Test (IEC 60885-3)

• Tan Delta (Dissipation Factor) Test (IEC 60840)

• Impulse Voltage Test (IEC 60060-1, IEC 60840)

• Bending Test

• Thermal Cycling Test

• Routine Tests (Manufacturing Checks)

• High Voltage DC Test (IEC 60502, IEC 60840)

• Insulation Resistance Test (Megger Test)

• Partial Discharge Test (for MV/HV cables)

• Pre-Commissioning & Field Tests

• VLF (Very Low Frequency) Testing (IEEE 400.2)

• DC Hi-Pot Test (IEEE 400.4)

• Tan Delta & PD Testing (for condition assessment)

• Sheath Integrity Test (for metallic sheaths)

6. Specialized Tests

• Partial Discharge (PD) Measurement (IEC 60270)

• Dielectric Spectroscopy (Frequency Domain Spectroscopy - FDS)

• Time Domain Reflectometry (TDR) for fault location

Conclusion

The selection of testing standards depends on the cable type (MV/HV/EHV), insulation material (XLPE, EPR, PILC), and application (underground, submarine, overhead). Compliance with IEC, IEEE, or national standards ensures safety and performance.
