## What is no load test of 3-phase induction motor?

No Load Test is an indirect method used for determining the efficiency and also to determine the circuit parameters of the equivalent circuit of the three-phase induction motors. The open-circuit test is performed on the transformer. The no-load test is the same as the open-circuit test performed on the transformer.

## What is full load of 3-phase induction motor?

3 phase 415V, at 0.8 pf, 1 Hp motor full load current = 1.3 Amps. 1 Phase 230V, at 0.8 pf, 1 Hp motor full load current = 4 Amps.

## What is load test on induction motor?

The load test on induction motor is performed to compute its complete performance i.e. torque, slip, efficiency, power factor etc.

## How do you calculate 3 phase load current?

3-Phase Calculations For 3-phase systems, we use the following equation: kW = (V × I × PF × 1.732) ÷ 1,000. Again, assuming unity PF and solving this equation for “I,” you get: I = 1,000kW ÷ 1.732V.

## What is a no load test?

The open-circuit test, or no-load test, is one of the methods used in electrical engineering to determine the no-load impedance in the excitation branch of a transformer. The no load is represented by the open circuit, which is represented on the right side of the figure as the “hole” or incomplete part of the circuit.

## How is a three phase induction motor tested?

By conducting the load test on three phase induction motor, the performance of the motor viz. slip, power factor, input, efficiency etc. at various loads can be studied. 1.

## What should the resistance of an induction motor be?

Three-Phase Induction Motor – Load tests Record the specifications of the Induction Motor (IM) Arrange and measure the resistance of the load rack in the same manner as in the previous experiment for 6 different readings. It should range from 500 Ω down to about 30 Ω.

## How to do a no-load motor test?

Lesson 15_et332b.pptx 7 No-load Test – Finds magnetizing reactance and combined friction, core and windage power losses. No-Load Test Procedure 1.) Apply rated voltage and frequency with no mechanical load. 2.) Measure current voltage and power. 3.) Uses same test instrument setup as locked-rotor test. Measure I L , V L and P T
