What are the main types of electric meters?
Electromechanical (Induction) Meters: Use electromagnetic induction to drive a rotating disk. Simple but vulnerable to environmental interference (e.g., humidity, thunderstorms).
Electronic Meters: Utilize electronic components for measurement, offering advanced features like prepayment, time-of-use billing, and anti-reverse flow. Require anti-interference design to prevent data errors. -
How do I choose the right electric meter?
Current Rating: Select based on basic current (e.g., 5A) and maximum rated current (e.g., 20A) to avoid overload damage.
Functionality: Match features like prepayment, networked meter reading, or anti-reverse flow to your needs.
Accuracy Class: Common classes include 0.2S, 0.5S, 1.0, and 2.0 (higher = more precise). -
What preparations are needed before installing an electric meter?
Ensure the location is well-ventilated and free of corrosive gases.
Gather tools: wrench, screwdriver, insulating tape, etc.
Turn off power before connecting inlet and outlet wires securely. -
How to detect electrical leakage?
Use an insulation resistance tester to check the meter and wiring. Low resistance indicates leakage.
