Voltage regulators provide 32 steps

Medium Voltage Distribution Voltage Regulator

Single Phase Voltage Regulators equipment is capable of measuring and correcting the voltage drops of the distribution lines caused by the current of the load on its own line impedance. They can be used in single-phase or three-phase systems, in substations, along the distribution lines, or at the entrance of a specific consumer, and improve the utility’s return on investment by increasing demand at off-peak periods.

The main body of the ZBSVR single-phase step voltage regulator is a single-phase autotransformer. It cooperates with the 32 steps change-over switch and American SEL intelligent voltage regulator controller to complete the voltage regulation function of 32 steps, and the voltage regulation accuracy of each gear is 0.625%. The change-over switch is connected with a specially designed reactor. When the gear is changed, the reactance provides current to offset the arcing current generated by switch shift. Therefore, the switching action will not have any impact on the internal insulating oil, in a real sense, the equipment is maintenance-free.

Definition

What is step voltage regulator & definition & theory?

The step-voltage regulator is basically an auto transformer that has its high-voltage winding (shunt) and low-voltage winding (series) connected to either aid or oppose their respective voltages, able to add or subtract voltage to provide a constant voltage output, which are the most common means used for regulating voltages.

How distribution voltage regulators work?

Power distribution voltage regulators maintain power distribution system voltages within a specified range. Regulated voltages ensure that electrical products and equipment will operate optimally. out of range electrical loads and long electrical distribution lines drop-down system voltages. distribution voltage regulators enable utilities to maintain voltage levels within acceptable ranges giving customers the assurance that electrical equipment will operate properly.

Voltage regulation calculation of distribution system?

Voltage Regulation= (1.06xPxLxPF) / (LDFxRCxDF)

P=Total Power in KVA. L= Total Length of Line from Power Sending to Power Receiving in KM. PF= Power Factor in p.u. RC= Regulation Constant (KVA-KM) per 1% drop.

What are the type of step voltage regulator?

Have two types of voltage regulating devices. The first of these is the Single-Phase Step voltage regulator (SVR). Typically on a high voltage lines distribution system, three SVR are required. equipped with an SVR on each line, to measure the voltage individually in each phase.

The second type of these is the three-Phase Step voltage regulator, which regulates all three phases of a power distribution system in unison. It is a voltage regulating device associated with a substation transformer.
