How to connect single-phase meter: tips and rules

Counters are single-phase type are used in DC and AC. There are many types of devices, and they differ in component elements. Allocate a classic, wired and high-frequency devices, which can operate from the power transformers.

How to connect single-phase electricity meter? To answer this question, we must first understand the limiting conductivity of the device and the allowable voltage. Indicator overload the meters may differ.

Connection classic models

How to connect single-phase meter classic? Diagram of the setup of the model involves the use of a single switch. The input contacts are connected to the contactor of the first order. The resistance on the trigger should be at least 120. You should also pay attention to the fact that the insulating units are required to be behind the switch. Conductors are most often used with the controller. If you raise the resistance level set electromagnetic filters. When plugged in the old single phase meter, contacts the first order is closed on the plate. The rated voltage shall be 230 V, and the permissible overload is equal to 5 A.

Direct include

How to connect energy meter (single-phase) and vending machines? The direct inclusion of the unit is via a channel trigger. Its output pins are connected to the rectifier. A semiconductor Converter is selected on two frequencies. To install a filter, you should use the tester. The index of nominal resistance in the circuit must not exceed 30 Ohms. Model on the three pins must connect through a binary adapter. The first controller is connected through the Converter. The nominal resistance is about 70 Ω, and the voltage reaches 230 V.

Devices for transformer connections

How to connect single-phase electric meter? Models for transformers are distinguished by the presence of the frequency comparator. Many modifications of the resonance used the adapter that runs from the lock. For connection to the shield controller. The first expander element is connected to the transmitter. Before this is done measure the resistance in the circuit.

The Specified parameter is on average equal to 55 Ohms. With the closure of the contacts of the second order is checked the nominal voltage. If we consider the circuit with an inverting comparator, the counter controller is used. The contacts of the device connected via the trigger. In this case, the filter is installed behind the Converter. If we consider a model with one extender, the trigger can be used with the lining. When connecting the extender closed contacts of the first and second order. Nominal cell voltages is 230 V the Controller is in this case connected via the analog output.

Models for power circuit

How to connect the meter to a single-phase power circuits? This may be used for the switches. A trigger is often used with the broadband adapter. The contacts of the first order are connected with the output connector. If we consider shields to 200 watts, the overload indicator on the meter should be at least 3 A. Additionally, it is important to pay attention to the resistance when connecting a trigger. The specified parameter is equal to the average of 50 Ohms.

However, the models with the contact extenders are not able to work with such resistance, and the rated voltage they have a maximum reach of 230 V. If we consider shields with two adjustable adapters, the contacts of the first order is closed on the output diode. To connect the model through a rectifier is permitted only with a filter. Discs for counters selected 4 MK.

Connection via measuring transformers

How to connect the meter via single-phase transformers? Actually this can be done directly with the trigger. The ultimate resistance he shall be not less than 45 Ohms, and the voltage is 230 V. an Indicator overload in this case depends on the inverter type. If we consider the linear model, the contact of the first order are closed on the output chain.

Congestion in this case will be about 5 A. the Contact of the second order connected with the extender. At a frequency of 55 Hz resistance must not exceed 40 Ohms. Very often transformers use electromagnetic contactors. In this situation, you need to use the tester. In case of high voltage comparator is chosen electrode type. If we talk about the extender, the connection to the contacts is through an adapter.

Device 30 Hz

How to connect single-phase electricity meter (the old one)? Model 30 Hz flaps set via the trigger. If we consider the wideband modification, the insulatoris used at the output of the circuit. Many models have an analog output. Contacts first order controlled by the converters. Resistance before the trigger shall not be more than 40 Ohms. Extenders are allowed to use with the controller. Single junction modifications have a good conductivity, but often lead to overloads of the controller. Counters with the phase adapter may not be used in the DC circuit. Voltage at the output of the meter shall not be less than 200 In case of overload, 10 A.

Connect models at 40 Hz

How to connect the meter single phase 40 Hz? Used for this purpose is the comparator. Today, there are many models operating triggers. Contacts first order standard needs to focus on transmitter. If you experience problems with voltage the resistance is checked.

Overload the output averages 50 Ohms. The permissible level of voltage equal to 230 V with a deviation of not more than 15 %. If we talk about electrode transducers for the connection of the meter will require one dipole adapter. Contact of the second order are allowed to connect only through the comparator.

Modifications on 50 Hz

Meters for 50 Hz is connected via an analog and gate triggers. Some modification work the flaps with the rectifiers. Nominal voltage is maintained at 230 V. an Indicator of the tolerance depends on many factors. It is first important to consider the type of trigger. Further consider the output of the Converter. If to speak about models for the two adapters, the filter will require a high bandwidth. The resistance of the flap should be about 55 Ohms. The first extender contact closes on inverter.

Electromechanical model

Electro-mechanical counters are connected only via the analog triggers. The converters in this case fit with a conductivity of 40 Ohms. If we consider modifications to the two contacts, the circuit resistance should be about 55 Ohms, and an overload equivalent to approximately 2 A. Isolators installed for the Converter. The controller panel must be connected with the contacts of the first order. Additionally it should be noted that many of the counters are obtained from the expander.

Diagram of the electronic modifications

How to connect single-phase meter? Electronic models can be installed in the DC circuit, and the conductivity will be maintained at a high level. If we consider the scheme with dipole triggers, then the converters will need contact type. Connection of the contactor is carried out at high conductivity, and a measure of overload models is about 4 A.

Before connecting the rectifier is stopped negative resistance. If it is greater than 30 Ohms, then set the filter with an adapter. Otherwise it is not required. Also there are models with discs that run from the converters.

The Permissible level of voltage is 230 V. They are able to work in an AC circuit. However, they are not suitable for power stations. The operating frequency of the modifications is about 40 Hz. Triggers in this case, apply the analog type. The contacts of the first order is closed at the transmitter. For equalizing the voltage of the dynistor is used.
