1.Application
The series single-phase meter is a kind of induction meter to measure the single phase current at the rated frequency of 50Hz. It is an indoor installed meter. Ambient temperature: 10°C to 50°C, relative humidity: below 85% (25°C). DT8 and DT862 series three-phase meter is an induction meter to measure the three-phase current at the rated frequency (50Hz). It is an indoor installed meter; Ambient temperature: -10°C to 50°C, except the first grade is under the working condition of 0 to 40°C. Relative humidity: below 85% (25°C).
2. Functions:
♦ Meter base: bakelite or steel
♦ Meter main cover: bakelite or PC transparent anti UV or AS transparent
♦ Meter terminal cover: short or extended ( bakelite or PC transparent anti UV or AS )
♦ Material which is moisture-resistant, fire-retardant, high temperature molded
♦ Meter register: 5 or 6 digits, May select uni-directional function
♦ Bearing: Jewell or double Jewell or Magnetic
♦ The die-casing frame is alloy aluminum, molding with excellent mechanical strength, stable structure
♦ Voltage components and current components, using double insulation structure, have good electrical characteristics;
♦ Error adjustment mechanisms have fine adjustment mechanism.
♦ Starting: Under rated voltage and frequency and when cos Φ=1.0, the disc will ceaselessly rotate when the load current is not over 0.5% of basic current.
♦ Running with no-load: When no current in the current circuit and 80- 110% of rated voltage across the voltage circuit the disc will not make a complete revolution.
♦ Power loss: With no current in the current circuit and under rated voltage and frequency, the power loss in the voltage circuit is no more than 1.5W.
♦ May select extended terminal cover, which is for protecting the safety while using.
