The JPSXXX-XXX-X series PQ-CT current transformers measure AC line current in circuits up to 600 Vac and nominal currents up to 1200 amps.
They are easy to install with their split-core design. The PQ-CT is ideal for use in High Performance Power Quality Monitoring (IEC 61000-4-30 Class A or S). It may also be used in other power meter- ing applications.
The JPSXXX-XXX-X may be field-installed inside distribution and control equipment such as switchboards and panelboards, or used in equipment designed for MV / LV substations, power quality meters, energy meters, branch circuit meters, PV monitoring, motor quality diagnostics, traction and data center use, etc. 테스트
◆ Install in accordance with ANSI/NFPA 70, “National Electrical Code” (NEC). Follow all local electrical codes.
◆ Only qualified personnel of licensed eletricians should install the current transformer (CT). Line voltages of 120 Vac to 600 Vac can be lethal.
◆ Do not install CTs where they block ventilation openings.
◆ Do not install CTs in the area of breaker arc venting.
◆ The current transformer cannot measure direct current (DC), and excessive DC will degrade AC measuring accuracy.
◆ Electrical codes prohibit installation of CTs in equipment where they exceed 75% of the wiring space of any cross-sectional area.
◆ The PQ-CT lead wires are considered Class 1 wiring (as defined by the NEC) and must be installed accordingly. They are not suitable for Class 2 wiring methods and should not be connected to Class2 equipment.
◆ If the equipment is used in a manner not specified by the manufacturer, the protection provided by the equipment may be
◆ Do not install the CT where it may be exposed to: temperaturesn below -40°C or above 80°C (-40°F to 176°F), excessive moisture, dust, salt spray, or other contamination.
◆ The PQ-CT may be damaged if dropped or subjected to impact. This can result in reduced accuracy.
