INTRODUCTION
MEWOI-ZD-P Series AC/DC Hipot Testing Is The Effective And Direct Way To Test Insulation Strength For Electric Equipment.It Check Dangerous Flaws And Make Sure Electric Equipment Continuous Working.It Typically Used To Test Insulation Strength For All Kinds Of Electrical Equipment,Components Like Capacitors,Insulation Materials. The Control Unit Should Be Worked Together With Testing Transformer. There Are Three Types Of Testing Transformers For Option. AC Hipot testing is the effective and direct way to test insulation strength for electric equipments,apparatus or machines.It checks dangeous flaws which assure electric equipment continuous working.Typical applications include testing of transformers, switchgear, cables, capacitors,aerial motors platforms,hot sticks bucket bricks,vacuum bottles and other related equipment like vacuum interrupters, blankets, ropes,gloves,hydraulics hose,instruments transformers generators. |
MAIN FEATURES
| 1,Various test transformers, such as oil-immersed transformer, dry transformer or SF6 gas transformer, can be configured according to user's requirements. |
| 2,High Voltage, Current, Low Voltage Current, Time, Four Ways of Measurement. |
| 3,Manual operation mode improves the safety and reliability of the product. |
| 4,Real-time display of high voltage voltage, high voltage current, low voltage current and time is intuitive and clear. |
| 5,It has the functions of zero position indication, power supply indication, work indication, timing indication, safety emergency button and so on. |
| 6,Perfect functions such as over-current protection, Zero-start protection, sound-light language alarm and warning, power supply protection switch, etc. |
| 7,A new type of time relay with a wider time range (1S~99H) |
| 8,The new current relay is more accurate and reliable to ensure the safety of people and equipment. |
| 9,The test capacity is less than 10 kVA, and a new type of engineering plastic box is adopted. |
