Product Description

Manufacture 30kv Cable Withstanding AC Hipot Tester High Voltage Hipot Tester Price

• 0.1Hz 0.02Hz Vlf Very Low Frequency Cable Withstand AC/DC Hipot High Voltage Test Set is designed and manufactured for electrical equipment very low frequency withstand voltage test.

• Very low frequency withstand voltage test is essentially an alternative of power frequency withstand voltage test. It is much smaller, lighter and portable than power frequency withstand voltage tester. It is proved home and abroad that 0.1Hz ultra-low frequency withstand voltage test can replace power frequency withstand voltage test.

• It can be applied for 10kV, 35kV, 300MW thermal power machine, 10kV, 35kV power transformer and other electrical equipment.

Specification:

• Max voltage output: refer to following table;

• Output frequency: 0.1Hz, 0.05Hz, 0.02Hz;

• Measurement accuracy: 2.5%;

• Positive and negative voltage peak errors < 2.5%RDG+0.3%FS;

• Voltage wave form distortion:<3%;

• Insulation resistance measurement error:<2.5%;

• Leakage current measurement error:<2.5%;

• Power supply:AC220V ± 10%, 50Hz/60Hz;

• Environment temperature: 0~50°C;

• Humidity:≤85%RH;

Operation

 

• Dual Booster Switching: Single booster for ≤30KV test, series connection for 30-80KV test, clear wiring guide included.
• Digital Parameter Setting: Large LCD screen displays voltage, current, frequency, test time; preset test voltage (10-80KV), frequency, and protection values.
   
• Automatic Boost & Timing: Automatically boosts to set voltage and maintains it for 1-60 minutes, test report printed upon completion. 
• Safety Protection: Overvoltage/overcurrent protection (shuts down within 20ms), mandatory grounding, and high-voltage door interlock.

Application Scenarios

 

1. Provincial, municipal, and county power grid maintenance teams: Handover and annual pre-testing of 10/20/35kV distribution network cables; easy operation in mountainous areas and underground tunnels, requiring no heavy power frequency equipment.

2. Cable and motor manufacturing plants: Insulation withstand voltage inspection of cross-linked cables and large and medium-sized generators; batch production line stability testing; standardized printing of factory reports.

3. Third-party power notary and testing agencies: Notarized withstand voltage testing for project handover; waveform and original data are complete and traceable, meeting CNAS laboratory testing and archiving requirements.

4. Overseas power transmission and transformation EPC projects: Supports 60Hz power supply, all-English operating interface, English test reports, and is compatible with Southeast Asian and European and American cable acceptance standards.

5. Photovoltaic and wind power booster stations: Routine insulation testing of 35kV outgoing cables and transformer substation cables within the site; suitable for operation in the field with only 220V residential power supply when there is no industrial mains power.

6. Metallurgical and chemical self-owned power plants: Regularly screen the insulation of high-voltage cables and large motors in the plant area to avoid production stoppages caused by insulation breakdown.
