III.Structural description

 

This instrument is a vertical three-box structure.

The lower box is the booster, i.e. power supply box. The output current has 1A, 5A and 100A gears. According to the primary current of the

measured transformer to choose the output gear of the booster. It is also equipped with coarse and fine regulator for current adjustment.

 

It is strictly prohibited to use the power supply box to exceed the current limit, otherwise it may cause permanent damage to theinstrument!

 

Micro standard current transformer. The panel has a primary current terminal, secondary current transfer switch; the upper box for the

measurement error line box: miniature transformer calibrator. On the panel there is a touch screen, set the function and display data; the measured transformer secondary terminals K1,K2; the measured transformer load (resistance) changeover switch, external load terminals. When the secondary load of the measured transformer is a load other than the designed load, the external load terminal can be connected to the required load value. In this case, the load knob should be placed in the external position.

 

The connections on the front and back of the three boxes are shown in the following diagram.

 

  Picture a                                                Picture b

 

IV.Usage

 

1. according to the above figure after connecting the cable line,

according to the measured transformer range, select the corresponding standard transformer range.

2. the lower box regulator is placed in zero position, turn on the power. Adjust the regulator to the required current value, read f, δ error.

3. the specific method of measuring the number of turns, the primary current is indicated in amperes, the secondary current is indicated in

milliamps. First of all, according to the size of the primary current of the measured transformer in the standard selection of the corresponding wiring jack, and then the formula: " primary rated current * primary turns * 1000 / secondary turns" to get the size of the output secondary current, the secondary switch to the corresponding gear calculated.

 

For example: a current transformer primary current of 3A, primary turns for 1 turn, secondary turns for 50 turns, then the primary jack should be selected 3A gear, calculated secondary switch gear 3 * 1 * 1000 / 50 = 60mA. secondary switch should be dialed to 60mA gear.Other small transformer turns measurement and so on. Based on the above method, we can measure many kinds of turns of the transformer, the fundamental approach to calculate the turns of the corresponding relationship, if the primary 40A1N

current transformer, secondary turns for 1000N, we conclude that the secondary current should be 40mA, but the standard primary wiring jacks do not have 40A, we will be commuted to the other corresponding gear to measure, only need to satisfy the corresponding relationship between the number of turns can also be used. Can be, for example, with the primary 30A (see the maximum range), secondary 30 mAto measure, but also with the primary 20A, secondary 20 mAto measure, but pay attention to the current operating range.

 

V.Precautions

 

1. access to the measured transformer, should be connected to the secondary first, and then connected to the primary. When removing the transformer, the primary should be removed first, then the secondary. And pay attention to whether the polarity is correct or not.

2. When measuring the error, the grounding wire of the instrument must be firmly grounded in the lower left part of the rear panel of the instrument, see Picture b.

 

Note: Please pay attention to the power supply access, L,N (fire wire, zero wire), must not be connected to the opposite.
