10kVA 50kV AC DC Hipot Test Set

Product Introduction

The Ministry of Machinery and Electronics' "Test Transformers" standard is the basis for the production of the MEYDJ-W10kVA-50kV Power Frequency AC/DC Withstand Voltage Test Device, which incorporates significant advancements over earlier comparable products. A new product line called the TDM(G) series lightweight AC/DC high-voltage test transformers was created from the MEYD(G) series test transformers and improved in accordance with the national standard "ZBK-41006-89." Compact size, light weight, integrated structure, extensive functionality, high adaptability, and easy operation are characteristics of this series. Insulation strength tests under power frequency or DC high voltage on various high-voltage electrical equipment, electrical components, and insulating materials are especially appropriate for power systems, industrial and mining firms, and research organizations. It is a necessary piece of equipment for testing at high voltages.

FAQ

1)What are the applicable scenarios for the MEYD-W10kVA/50kV Power Frequency Withstand Voltage Test Device?

Answer: The MEYD-W10kVA/50kV power frequency withstand voltage test set belongs to the MEYD series of lightweight oil-immersed test transformers. It is particularly suitable for power systems, industrial and mining enterprises, research institutions, etc. It is primarily used for conducting insulation strength tests under power frequency or DC high voltage on various high-voltage electrical equipment, electrical components, and insulating materials. It is an indispensable and important piece of equipment in high-voltage testing.

2)What are the grounding requirements for the second and third stage test transformers when conducting cascaded tests using the MEYD-10kVA/50kV power frequency withstand voltage test set?

Answer: During cascaded testing, the X terminals of the low-voltage windings, the F terminals of the measuring windings, and the X terminals (high-voltage tails) of the high-voltage windings for the second and third-stage test transformers must all be connected to the housing of the respective stage's test transformer. Additionally, the housings of the second and third-stage test transformers must be grounded via insulating supports.

3)When conducting power frequency withstand voltage tests with the MEYD-W10kVA/50kV power frequency withstand voltage test apparatus, how should abnormal conditions be handled?

Answer: During voltage increase or withstand voltage testing, if any of the following abnormalities occur-such as significant oscillation of the voltmeter needle, charred insulation or smoke emission, or unusual sounds from the test specimen-immediately reduce the voltage and disconnect the power supply. After stopping the test, investigate the cause. Upon test completion, return the voltage regulator to zero position at a steady rate within several seconds before disconnecting the power supply to ensure equipment and personnel safety.
