Product Detail

Product Description
The RVR-1 single-phase step voltage regulator is an advanced tap-changing autotransformer designed for precise voltage regulation on 11kV overhead distribution lines. Manufactured exclusively in China, it automatically adjusts line voltage within a range of ±10% in 32 fine steps (approx. 5/8% per step), ensuring stable power supply under varying load conditions. Suitable for 50/60Hz systems, it offers flexible configurations for pole-mounted, pad-mounted, or substation installations.

Product Features

Precise Voltage Control

  • 32-step tap changer (±10% range) for accurate voltage stabilization.

Wide Compatibility

  • Supports system voltages from 2,500V to 19,920V (60–150 kV BIL) and currents up to 1,665A.

Advanced Digital Control

  • Programmable settings for voltage limits, communication protocols, and data logging.

Flexible Installation

  • Pole-mounted brackets, pad-mounted bolts, or substation bases (elevating platforms optional).

Robust Design

  • Internal tap windings and optional ratio correction transformer for diverse grid applications.

Advantages

  • High Reliability – Ensures consistent voltage output in harsh environments.
  • Customizable – Adaptable to various system voltages and control requirements.
  • Low Maintenance – Automated tap-changing reduces manual intervention.

Application Scenarios

  • Rural/Urban Power Grids – Compensates for voltage drops in long-distance overhead lines.
  • Industrial Zones – Stabilizes voltage for heavy machinery and sensitive equipment.
  • Renewable Energy Integration – Manages fluctuations in solar/wind power-fed grids.
  • Substations – Enhances voltage control in distribution networks.

Why are the ground fault point and the accident point not at the same location?
Why are the ground fault point and the accident point not at the same location?
Fault Transfer VoltageIn low - voltage distribution systems, there is a type of personal electric shock accident where the accident occurrence point and the system fault point are not at the same location. This kind of accident occurs because after a ground fault happens elsewhere, the generated fault voltage is conducted to the metal casings of other equipment through the PE wire or PEN wire. When the fault voltage on the metal casing of the equipment is higher than the human - body safe voltag

What is reactive power measurement?
The power which exists in the circuit when the voltage and current are out of phase to each other, such type of power is known as the reactive power. The formula measures the reactive power in the circuitReactive Power Measurement & VarmetersReactive power measurement is critical as it indicates circuit power loss: low reactive power worsens load power factor, increasing system losses. Varmeters (volt-ampere reactive meters) measure reactive power and are categorized by circuit phases:Single

How to Design and Install a Solar PV System?
Design and Installation of Solar PV SystemsModern society relies on energy for daily needs like industry, heating, transport, and agriculture, mostly met by non-renewable sources (coal, oil, gas). However, these cause environmental harm, are unevenly distributed, and face price volatility due to limited reserves—driving demand for renewable energy.Solar energy, abundant and capable of meeting global needs, stands out. Standalone PV systems (Fig 1) offer energy independence from utilities.

What are the common faults that occur when low-voltage current transformers are combined with other power equipment?
What are the common faults that occur when low-voltage current transformers are combined with other power equipment?
Low-voltage current transformers, as indispensable measurement and protection devices in power systems, often encounter various faults when used in combination with other power equipment due to environmental factors, equipment linkage issues, and improper installation and maintenance. These faults not only affect the normal operation of power equipment but may also endanger personal safety. Therefore, it is necessary to gain an in-depth understanding of fault types, judgment methods, and prevent
