HVM was founded in Austria in 1941 and relocated to Aachen, Germany, after World War II.
HVM engaged in the production and maintenance of transformers, and began manufacturing core reactors and other reactor application products in the 1970s.
In addition to marketing its products globally, HVM is also a supplier for Siemens, Schneider, and ABB.

Hans Von Mangoldt has the capability to produce these types of reactor products, backed by over 20 years of successful experience. Mangoldt reactors are characterized by low noise and high efficiency during operation, with primary applications in the following industrial sectors: cement and steel plants, power factor compensation for electric furnaces, the chemical, petrochemical, and rubber industries, automotive assembly, and public transportation systems.
Additionally, they are used in other areas, including high-rise buildings, hospitals, public water supply systems, flicker compensators, active filters, wind turbines, engines, and dynamic compensation systems.

Design Standards

Since the operating conditions of the reactor in the power grid are unpredictable, all reactor designs should be based on the worst-case scenario and comply with the tolerances specified by the IEC 60289 international standard. Given the absence of a universally accepted standard for power quality measurement, the definition of such worst-case scenarios can only be determined through agreements between major power factor capacitor suppliers and Mangoldt. The following design standards have been proven reliable over the years.

• Inductance Tolerance: -2% ... +3% of LN
• Fundamental Current I1: 1.06 · ICN or 1.10 · ICN (considering 6% or 10% overvoltage)
• Assumed Harmonic Voltage Distortion: UH3 = 0.5%; UH5 = UH7 = 5.0% (based on nominal voltage UN)
• Thermal Current Ith: 1.05 · Irms (related to maximum tolerance and capacitor aging)
• Core Linearity Limit ILin: 1.20 · I1...7 (affects switching transient tolerance under full harmonic load conditions)
• Assumed Ambient Temperature: 40°C
