150kV AC DC Digital Voltage Divider

Product Introduction

This product is a high-voltage measurement device that uses a resistive-capacitive equal-potential shielded voltage divider. Pulse high voltage, lightning high voltage, and power frequency high voltage are its main applications. It is the recommended substitute for high-voltage AC/DC voltage dividers. It is perfect high-voltage measuring equipment for power plants, substations, producers of high-voltage electrical equipment, and high-voltage testing labs because of its straightforward operation, easy-to-use display, high accuracy, small size, and light weight.

Through the use of instrument cables, this AC/DC voltage divider is connected to the high-voltage measurement terminal, allowing for safe and convenient distant readings. This series uses specialized shielding technology to reduce high-voltage interference on readings, resulting in great stability and linearity. It has a high input impedance and outstanding linearity.
The design minimizes internal partial discharge while achieving a more compact construction, less weight, and increased dependability through the use of imported filler materials. It is quite portable due to its tiny size and light weight, which makes on-site testing operations much easier.

FAQ

1)What critical connection steps must be completed before using the MEFRC-W150kV AC/DC Digital Voltage Divider?

Answer: First, securely ground the divider's ground terminal to prevent high voltage from reaching the meter housing and causing electric shock. Next, connect the high-voltage lead above the equalizing ring and tighten it with the terminal screw to ensure the test lead does not protrude or lift (if possible, place them under a metal shield to reduce interference). Finally, connect the signal connector of the divider to the LCD display head. Only after completing these connections should you turn on the power and select the measurement mode.

2)Are there special requirements before disconnecting the cables after measuring DC voltage with the MEFRC-W150kV AC/DC Digital Voltage Divider?

Answer: Yes, special requirements apply. After DC measurement, first verify that the LCD display reads approximately "0.XXX". If the test object includes filter capacitors, fully discharge them first. Once the divider's reading approaches zero, use a discharge rod to discharge the divider. Only after completing these steps may you proceed with disconnecting cables or subsequent tasks.

3)How should the MEFRC-W150kV AC/DC Digital Voltage Divider be maintained during long-term storage to protect the equipment?

Answer: First, return the device to its aluminum alloy case and store it in a dry environment to prevent moisture exposure. Second, the LCD display contains a built-in lithium battery that requires charging at least once per month for approximately 3 hours to prevent battery damage from deep discharge. Additionally, handle the device with care to avoid impacts or compression. Maintain the surface cleanliness to prevent contamination from affecting performance.
