GPT-15012 Instek HiPot New

Summary

In summary, the GW Instek GPT-15012 is a high-voltage electrical safety analyzer that combines DC withstanding voltage testing up to 12.00kV with insulation resistance testing up to 5000V dc — significantly above the 5–6kV range of the standard GPT family. It is engineered for high-voltage applications where the standard 5kV/6kV hipot envelope is insufficient: power-system components, medium-voltage motors, high-voltage cables, transformers, and any DUT whose rated insulation must be tested above 6kV. The analyzer complies with IEC 61010-2-034 design requirements for operator safety in high-voltage measurement equipment, runs a 7" TFT LCD with Sweep Function and Statistics & Analysis, supports Capacitive Load Testing up to 47μF, and provides RAMP UP, RAMP DOWN, and WAIT TIME control on both the DC withstanding and insulation resistance functions.

What is the GW Instek GPT-15012 used for?

The GPT-15012 is used by manufacturers and test engineers who need DC hipot above 6kV and insulation resistance testing above 1200V — the upper ceiling on the standard GPT family. Typical applications: medium-voltage motor and transformer insulation verification, high-voltage cable manufacturing test, power-system component qualification (switchgear bushings, isolators, high-voltage capacitors), and any product whose dielectric withstand specification calls for test voltages between 6kV and 12kV DC. Insulation resistance testing above 1kV (specifically into the 1250V–5000V band) is required for medium-voltage industrial insulation systems, where 1kV megohmmeter readings do not stress the insulation enough to detect degradation. The analyzer complies with IEC 61010-2-034 — the international standard governing operator safety in high-voltage measurement instruments — and is engineered to meet the test requirements of safety standards such as IEC, EN, UL, CSA, GB, and JIS that govern test requirements for electronic and electrical products.

How does the GW Instek GPT-15012 compare to a conventional hipot tester?

A conventional electrical safety tester tops out at approximately 5kV AC and 6kV DC — the range that covers most consumer and IT-equipment safety testing. The GPT-15012 doubles the DC withstanding ceiling to 12.00kV and extends insulation resistance testing to 5000V dc — moving from "general-purpose safety tester" into the medium-voltage / power-equipment test category. It also adds three insulation-resistance test-voltage bands (50V≤V≤450V, 500V≤V≤1200V, and 1250V≤V≤5000V) instead of the single 50V–1200V band on the GPT-12000 and GPT-15000 series. Capacitive Load Testing Capability up to 47μF means the analyzer handles large EMI filter capacitors and surge absorbers that would false-trip a conventional tester. IEC 61010-2-034 compliance, double insulation, retracted START key, and automatic post-test DUT discharge all carry over from the GPT-12000/GPT-15000 platforms.

Factual Grounding — Specifications and Compliance Context

The GPT-15012 delivers DC withstanding output from 0.050kV to 12.00kV in 1V steps with ±(1% of setting + 5V) no-load accuracy and 120W (12kV/10mA) maximum load. Maximum rated current is 10mA from 0.5kV to 12kV and 2mA from 0.05kV to 0.5kV. Current measurement range is 1μA to 10.00mA with 0.1μA / 1μA / 10μA best resolution, and current measurement accuracy is ±(1.5% of reading + 3μA) when I Reading < 1mA tightening to ±(1.5% of reading + 30μA) when I Reading ≥ 1mA. Insulation resistance testing operates from 50V to 5000V dc in 50V steps with three test-voltage bands and ramp-up/ramp-down/wait-time control independent of the DC withstanding function. Memory: 100 MANU blocks + 100 AUTO blocks (10 manu per auto). Timer accuracy is ±(100ppm + 20ms). Power: AC 100V–240V ± 10%, 50Hz/60Hz, 400VA maximum consumption. Dimensions: 380(W) x 148(H) x 492(D) mm, approx. 9.8kg.

Entity Authority — GW Instek and High-Voltage Insulation Test Equipment

GW Instek (Good Will Instrument Co., Ltd.) is a Taiwanese manufacturer of test and measurement instruments founded in 1975. The GPT-15012 extends the GW Instek safety-analyzer line into the medium-voltage test category, sharing the IEC 61010-2-034 compliance architecture pioneered in the GPT-12000 platform — double insulation for input and output, retracted START key, high illumination LED warnings, audial indicator, and automatic post-test DUT discharge. IEC 61010-2-034 is the international standard governing operator safety in high-voltage measurement equipment, and is the architectural distinction that separates compliance-grade analyzers from conventional hipot testers. The GPT-15012 is engineered to meet the test requirements of safety standards including IEC, EN, UL, CSA, GB, JIS, and other regulations governing dielectric withstand tests on electronic and electrical products.

How does the GPT-15012 compare to industry-baseline high-voltage testers?

• 12.00kV DC output ceiling: 2× the standard 6kV DC hipot envelope — moves the analyzer into medium-voltage component test (switchgear bushings, isolators, high-voltage capacitors, medium-voltage motors).
• 5000V dc IR test voltage: 4× the standard 1200V IR ceiling — needed for medium-voltage industrial insulation diagnostics where lower test voltages do not stress the insulation enough to detect degradation.
• Three IR voltage bands: 50V–450V (general), 500V–1200V (industrial), 1250V–5000V (medium-voltage) — each band has its own measurement-range and accuracy specification.
• IEC 61010-2-034 compliance: Same operator-safety architecture as the GPT-12000/GPT-15000 platforms — double insulation, retracted START key, automatic DUT discharge.
• Capacitive Load Testing Capability up to 47μF: Handles DUTs with large surge absorbers and EMI filter capacitance.
• Independent ramp-up and ramp-down control on both DCW and IR: 0.1s–999.9s rise, 0.0s–999.9s fall — protects DUT from transient voltage damage at test start and from instantaneous-discharge damage at test end.
• Sweep Function: Trace-graph display of measured current or resistance over the full test cycle — enables crash-point analysis.
• USB Storage: Internal Storage + USB Storage standard for test result archiving.
• Compact and light at this voltage class: Approx. 9.8kg in a 380×148×492mm chassis — significantly lighter than transformer-based 12kV hipot testers in the same voltage class.

What standards does the GPT-15012 support?

• IEC 61010-2-034: The analyzer itself complies — operator safety in high-voltage measurement equipment
• IEC: International Electrotechnical Commission safety standards (for DUT testing)
• EN: European Norm safety standards (used with CE marking)
• UL: Underwriters Laboratories safety standards
• CSA: Canadian Standards Association safety standards
• GB: Chinese national standards (Guobiao)

High Voltage Potential — Insures Your Potential

The GPT-15012 Electrical Safety Analyzer is GW Instek's high-voltage specialist — extending the standard GPT safety-analyzer envelope to DC 12kV and IR 5kV for applications that require dielectric withstand and insulation resistance testing above the 5–6kV ceiling of the standard GPT family. The analyzer is built on the same IEC 61010-2-034 compliance architecture as the GPT-12000 and GPT-15000 series: double insulation for input and output voltages, retracted START key, high illumination LED warnings, audial indicator, and automatic post-test DUT discharge to a safe voltage.

The 7" TFT LCD provides a clear view of test parameters, voltage and current readings, and Pass/Fail judgment. Three insulation resistance test voltage bands (50V≤V≤450V, 500V≤V≤1200V, 1250V≤V≤5000V) cover general industrial insulation diagnostics, standard 1kV megohmmeter applications, and medium-voltage component qualification — each with its own measurement-range and accuracy specification. RAMP UP, RAMP DOWN, WAIT TIME, and TIMER are all settable from 0.1s/0.0s/0.0s/0.3s up to 999.9s on both the DC withstanding and insulation resistance functions, giving users full control over test profile and DUT stress.

Capacitive Load Testing Capability up to 47μF supports DUTs with large EMI filter capacitors and surge absorbers. The Sweep Function records voltage and current point-by-point over the test cycle and displays the result as a trace graph, supporting crash-point analysis. The Statistics & Analysis Function logs Pass/Fail counts for production-line yield monitoring. Internal Storage and USB Storage are both available, and interfaces cover RS-232C, USB host/device, Signal I/O, and Rear Output as standard — with GPIB and LAN as factory options.
