The Megger HV Test Set series covers DC field cable testing in four voltage classes, 50, 80, 110, and 120 kV, in a modular two-unit (operation unit + HV unit) portable form, with both analogue and digital metering options available from the same OEM [S1].
For factory-floor electrical-safety compliance work, the METREL MI 3394 CE MultiTesterXA combines high-voltage testing with continuity, insulation resistance, substitute/differential/touch/PE leakage, discharge time, and functional power (P/S/Q, cos fi, ThdU, ThdI, PF) on a single 4.3 inch touch-screen platform, rated for AC 5.1 kV at 500 VA and DC 6 kV hi-pot [S2]. Budget dielectric-withstand instruments from Shenzhen Chuangxin (CX / Chuangxin brand) sit in a 1.00 to 5,000.00 USD/set FOB price band, with monthly supply from 100 to 1,000 sets [S3][S4].
Voltage Class and AC vs DC: The First Cut
Field cable testing at 50 to 120 kV DC is the domain of the Megger HV Test Set, built for paper-insulated mass-impregnated cable checks per IEEE 400-2012 and IEC 60060-3, and cable-sheath testing per IEC 60502 / IEC 60229, with the modular 50/80/110/120 kV version matching the standard U0 test tiers used in distribution [S1]. For routine production-line safety and CE certification on appliances, machines, and switchboards, AC hi-pot up to 5.1 kV at 500 VA plus DC 6 kV (as on the METREL MI 3394) is the typical operating envelope, and is what the IEC 60335 / IEC 60950 / IEC 61439 family of end-product standards call out for routine production tests [S2].
Buyers should treat AC and DC as non-interchangeable: DC test sets accumulate space charge and are used for long cable runs and sheath integrity, while AC hi-pot stresses insulation the way service voltage does and is the default for short winding, apparatus, and PAT-style production tests. Pairing a 5 kV AC PAT instrument with an XLPE cable acceptance test is a category error: the high voltage tester duty and the voltage class must match the cable or apparatus under test, not the other way around.
Test Functions Beyond Withstand: One-Box vs Modular
The METREL MI 3394 packs high-voltage (programmed AC/DC and optional A 1560 burn test), 4-wire continuity with selectable test current at 0.2 A, 4 A, 10 A, and 25 A, insulation resistance, substitute/differential/touch/PE leakage current, discharge time, and full functional power analysis (P/S/Q, V, I, cos fi, frequency, ThdU, ThdI, PF) into a single 4-wire, 4.3 inch LCD chassis with microSD support up to 32 GB [S2]. RS232, USB, and Bluetooth are all available for download, upload, and remote control, and the unit works on TT, TN, IT, and 115 V supply systems [S2].
By contrast, the Megger HV Test Set is a single-purpose DC cable tester, modular (operation unit + HV unit), portable, and qualified for on-site use, with a small footprint and low weight relative to its 50 to 120 kV output class [S1]. The CX/Chuangxin entry-level RK2674A and HV withstanding families target a different price point, FOB 1.00 to 5,000.00 USD/set and 1.00 to 600.00 USD/set respectively, with monthly supply 100 and 1,000 sets, and are pitched at routine dielectric withstand rather than full functional test [S3][S4].
Standards Fit: Which Tester Goes With Which Job
Megger explicitly maps the HV Test Set to IEEE 400-2012 and IEC 60060-3 for cable testing, IEEE 62.1 and IEEE 95 for electrical equipment, and IEC 60502 and IEC 60229 for cable sheaths and outer jackets [S1]. The METREL MI 3394 is positioned for CE certification of electrical appliances, machines, and switchboards during production, with hi-pot and continuity that align with the safety-test sequence in IEC 60335-1, IEC 60204-1, and IEC 61439-1 [S2]. For end-product safety in information-technology and audio/video equipment, hi-pot figures typically reference IEC 60065 / IEC 62368-1, and Shenzhen Chuangxin's "Dielectric Strength Test Device with metal bar made according to IEC60065 Figure 6" is a directly named accessory in their catalog [S3].
Insulation-resistance pre-checks and low-voltage continuity are often done with a separate instrument before hi-pot, which is why insulation testers and hipot sets are commonly specified as a matched pair. A buyer building a single test bay usually pairs a loop tester or insulation tester for pre-checks with a dedicated hi-pot for the withstand step, rather than asking one box to do both at full voltage class.
Selection Comparison: Field, Production-Line, and Budget
Three realistic options bracket the 2026 market: (a) Megger HV Test Set for DC cable acceptance and sheath testing in the 50 to 120 kV class, portable, analogue or digital metering, modular, per IEEE 400 / IEC 60060-3 [S1]; (b) METREL MI 3394 CE MultiTesterXA for factory electrical-safety CE testing on appliances, machines, and switchboards, AC 5.1 kV / 500 VA + DC 6 kV, with full leakage, continuity at 0.2 to 25 A, and functional power on a 4.3 inch touch panel [S2]; (c) CX / Chuangxin RK2674A and HV withstanding family for routine AC/DC dielectric withstand on a tight budget, FOB 1.00 to 5,000.00 USD/set or 1.00 to 600.00 USD/set, supplied at 100 or 1,000 sets/month from Shenzhen [S3][S4].
The decision pivot is voltage class and test type. Anything above 6 kV (cable commissioning, sheath integrity, mass-impregnated cable) belongs in the Megger 50 to 120 kV DC camp. Anything in the 5 to 6 kV hi-pot range with full PAT/CE leakage and functional power analysis goes to the METREL class. Anything in the benchtop, IEC 60065 Figure 6 dielectric bar / glow-wire / ball-pressure workspace goes to the Shenzhen Chuangxin instruments, which also overlap the IEC 60695-2-10 glow-wire product line [S3].
Who Should NOT Buy the Mainstream Option
Do not specify a METREL MI 3394 class instrument for DC cable commissioning above 6 kV, its DC hi-pot ceiling is 6 kV and its AC hi-pot is 5.1 kV at 500 VA, so it cannot reach the 50 to 120 kV DC levels IEEE 400-2012 calls for on paper-insulated or XLPE distribution cable [S2][S1]. A deadweight tester or comparable pressure instrument is also the wrong tool entirely, despite sharing the "tester" word: it is a pressure reference, not a voltage source. Buyers asking one instrument to cover both pressure calibration and high-voltage withstand end up with two under-spec'd boxes instead of two right-sized ones.
Equally, do not specify a Megger HV Test Set for routine CE production-line safety testing of small appliances, its 50 to 120 kV DC output class is far above what IEC 60335-1 hi-pot requires, and it lacks the leakage, continuity, and functional power channels the MI 3394 delivers in a single 4-wire test sequence [S1][S2]. For shop-floor dielectric testing only, the CX/Chuangxin FOB 1.00 to 5,000.00 USD/set band is a better fit than either, with the IEC 60065 Figure 6 metal-bar accessory shipping in the same Shenzhen catalog [S3].
Vendor Sourcing Landscape as of 2026-08
Established Western OEMs (Megger, METREL) continue to ship modular and multi-function platforms into 2026 trade shows: Megger is exhibiting the HV Test Set line at InnoTrans 2026 (22 to 25 September 2026, Berlin, Hall 17, Stand 200), and METREL is taking the MI 3394 to NordBau 2026 (9 to 13 September 2026, Neumünster) and INELTEC 2026 (9 to 10 September 2026, Zürich, Hall 4, Stand F11) [S1][S2]. Rectifiers & Electronics (RE), New Delhi, lists specialized HV products including AC high-voltage spark testers, double-voltage double-frequency test sets, electronic load banks, and impulse voltage generators, with industry applications covering heavy wire and cable manufacturing, transformer testing, control panel and switchgear testing, CT/PT, motor and generator testing, insulator materials, GIS and switchgear, power generation, T&D, and rail [S5].
Shenzhen Chuangxin Instruments (Guangdong, China Mainland) supplies CX / Chuangxin branded HV testers alongside Standard Test Finger, Plug and Socket Gauges, Spring Impact Hammer, Glow-Wire Test Apparatus (IEC 60695-2-10), Ball Pressure Test Device, Go/No-Go Gauge, and ESD Gun, with monthly capacity of 100 or 1,000 HV test sets and FOB 1.00 to 5,000.00 USD/set on RK2674A and 1.00 to 600.00 USD/set on the HV withstanding family [S3][S4]. RE was founded in 1970 and is presenting more than 50 years of HV testing equipment experience on its 2026 product pages [S5].
