The power frequency withstand voltage test is the most stringent, effective, and direct method for determining the insulation strength of electrical equipment.It can detect those high-risk concentrated defects that have a decisive impact on determining whether power equipment can continue operating, thereby ensuring the insulation level of the equipment and preventing insulation accidents from occurring.

This device is designed according to the latest national standards for the power industry and features advanced performance as a pressure test instrument. It is used to conduct insulation strength tests on various electrical products, electrical components, insulating materials, etc., at specified voltages to evaluate the insulation level of the product and identify any insulation defects in the sample. It also measures the ability of the product to withstand overvoltage conditions.

• Monitoring Functions: High Pressure Voltage, Low Pressure Current, Zero Position Indication, Power Supply Indication, Operating Indication, Timing Indication
• Protection Functions: Overflow Protection, Zero Position Startup Protection, Audible and Visual Alarm Reminders
• Uses a new type of time relay with a wider timing range (1 sec to 99 hrs)
• Adopts new current relays for more precise and reliable performance, ensuring personal and equipment safety.
• The high-voltage coil of the test transformer is cylindrical with multiple layers in a tower configuration, made from high-quality polyester varnish-coated wire and high-pressure insulation material.
• Test transformers (above 6kVA) equipped with removable iron cores.Lightweight, compact, easy to move, and featuring superior performance.

Conditions of Use:

1. The workplace should be free from gases, steam, chemical dust, and other explosive or corrosive media that severely affect insulation.
2. Ambient temperature -20 to +50°C
3. Ambient Humidity ≤85% RH (No Condensation)

Control Panel: 5KVA Test Oil-Immersed Transformer 50KV

Notes: If there are specific parameter requirements, it can be designed and manufactured according to the user's technical parameters.
