产品简介

Voltech电流互感器CT1000,系闭环式电流互感器。其具备两个两流档位,可针对*大100A和*大1000A两档电流进行量测,即保证了宽量程,又保证了高精度,是实验室功率分析仪的一大助手。可以非常方便地与voltech的PM系列功率分析仪连接,如PM1000+、PM3000A、PM6000等。

产品详细信息

Voltech电流互感器CT1000
The CT1000 is a toroidally wound AC current transformer which extends the range of Voltech power analyzers to 1200A rms.
Close tolerance current ratios provide a measurement accuracy of better than 0.2% making the CT1000 suitable for precision grade measurements.
The CT1000 is housed in a fully insulated, shock-resistant casing with a core aperture which accommodates large diameter cables or rectangular busbars. To minimize the risk of electrical shock, the CT1000 has 4mm safety sockets for the leads which connect it to the power analyzer. In addition, a novel over-voltage protection circuit limits the voltage on the
output terminals to 50V peak if the transformer secondary winding is inadvertently
open-circuited.
Specification
  • Frequency range: 45Hz to 1kHz
  • Current range: 100:1 ratio: 10A to 120A rms. 1000:1 ratio: 100A to 1200A rms
  • Maximum input current: 1000A continuous 2000A for 1 hour
  • Accuracy (23°C ± 5°C): ± 0.2% of specified ratio
  • Phase error (23°C ± 5°C): Better than ± 0.1° at 50Hz
  • Maximum burden: 0.15VA for specified accuracy (equivalent to the input of any Voltech power analyser plus the test leads provided).
  • Dielectric strength: 4kV at 50Hz for 1 minute
  • Temperature range; Operating: -10°C to +50°C Storage: -25°C to +85°C
Operation
  • For primary circuit currents between 10A rms and 120A rms use the output sockets on the CT1000 marked 100:1
  • For primary circuit currents between 100Arms and 1200Arms use the sockets marked 1000:1
When the CT1000 is used with Voltech power analyzers, the analyzer's scaling function can be used to automatically scale measurement by a factor of 100 or 1000 as appropriate.
