What is Blocked Rotor Test of Induction Motor?

Blocked Rotor Test Definition

The blocked rotor test of an induction motor is defined as a test to find the leakage impedance and other performance parameters.

Purpose of Blocked Rotor Test

It determines torque, motor characteristics, and short-circuit current at normal voltage.

Testing Procedure

During the test, the rotor is blocked, and low voltage is applied to the stator to measure voltage, power, and current.

Effect on Impedance

Rotor position, frequency, and magnetic dispersion can impact the measured leakage impedance.

Short Circuit Current Calculation

The test helps calculate short circuit current for the normal supply voltage by measuring specific parameters.

Cost Differences and Performance Comparison of 35kV New Energy Transformers Based on Dry-Type, Mineral Oil, and Vegetable Oil

Cost Differences and Performance Comparison of 35kV New Energy Transformers Based on Dry-Type, Mineral Oil, and Vegetable Oil

For users, when purchasing a 35kV new energy transformer, choosing between dry-type, mineral oil-filled, or vegetable oil-filled types involves multiple considerations. These include user habits, maintenance-free performance, safety and fire resistance, volume and weight, among others. However, cost differences are undoubtedly one of the most crucial factors.To illustrate the issue intuitively, this paper selects a three-level energy efficiency dual-winding new energy transformer with a rated ca

What is the connection group of a transformer?

What is the connection group of a transformer?

Transformer Connection GroupThe connection group of a transformer refers to the phase difference between the primary and secondary voltages or currents. It is determined by the winding directions of the primary and secondary coils, the labeling of their start and end terminals, and the connection mode. Expressed in a clock-like format, there are 12 groups in total, numbered from 0 to 11.The DC method is commonly used to measure the transformer's connection group, mainly to verify whether the con

What is the sequence for powering down the transformer?

What is the sequence for powering down the transformer?

The sequence for shutting down a main transformer is as follows: when de-energizing, the load side should be shut down first, followed by the power supply side. For energizing operations, the reverse order applies: the power supply side is energized first, then the load side. This is because: Energizing from the power supply side to the load side makes it easier to identify the fault range and take prompt judgment and handling measures in case of a fault, preventing the fault from spreading or e

What are the methods for switching operations of station transformers?

What are the methods for switching operations of station transformers?

Let's take an auxiliary power system with two station transformers as an example. When one station transformer needs to be out of service, there are two operation methods: non-interruptive power supply and instantaneous power interruption. Generally, the method of instantaneous power interruption on the low-voltage side is preferred.The operation method for instantaneous power interruption on the low-voltage side is as follows:Open the 380V power incoming circuit breaker of the corresponding sec
