How do you attach a meter to a CT?

How do you attach a meter to a CT?

Key Points

1. Install CTs on the phase conductor that corresponds to the voltage input phase.
2. Install CTs with the arrow or label ‘This side toward source’ facing towards the breaker feeding the load.
3. Connect the white and black CT leads to the corresponding CT input terminals with the white and black dots.

How do you install a three phase meter?

Installation of 3 Phase kWh Energy Meter

1. R = RED Phase / Live Wire from the source supply voltage.
2. Y = YELLOW Phase / Live Wire from the source supply voltage.
3. B = BLUE Phase / Live Wire from the source supply voltage.
4. Line or IN = Incoming Phase / live or Neutral from the source supply voltage.

What is 3 phase wiring in a house?

In this three phase wiring, lighting, small-appliance loads and receptacles are often connected between phase and neutral while larger equipments such as air conditioners and electric heaters are connected between two phases (i.e., phase to phase).

How do I connect to my electric meter?

Instructions

1. Connect the Line Hot Wires. When the utility company connects the meter, the technician will bring the service wires down from an overhead mast or into the meter box through an underground feed.
2. Connect the Load Hot Wires.
3. Connect the Ground Wire.
4. Connect the Neutral Wires.

How is CT connected?

A current transformer is connected in series to the current-carrying conductor and an ammeter is connected to its secondary. The ammeter is arranged to give a full deflection with either 5A or 1A depending on the turns ratio of the CT. The ammeter’s scale is adjusted according to the turns ratio.

What is CT operated energy meter?

The 3 Phase CT Operated Trivector Meter is designed for metering of LT consumers and feeders. The meter has advanced data and tamper recording capabilities and is provided with communication ports. The software is available for data collection, load survey analysis and energy management applications.

How do you connect a meter?

How do I know if a connection is 3-phase?

What you need to identify is the MAIN SWITCH. In most instances, the main switch will either be what is referred to as 1-pole wide or 3-poles wide. If your Main Switch is 1-pole wide, then you have a single phase power supply. Alternatively, if your Main Switch is 3-poles wide, then you have a 3-phase power supply.

Do homes have 3-phase power?

Residential homes are usually served by a single-phase power supply, while commercial and industrial facilities usually use a three-phase supply.
