====== 1-ph current transformer ====== **Split core current transformer 50A ** {{ :hiq_energy:hems:hardware:ct.png?nolink |}} | Model number: ^ CT-1-E-50 | | Connect to: | [[en:hiq_hw:pm1-e-d-ct|PM1-E-D-CT]] | | ::: | terminals 1 -2 | | Mounting: | on wire | | Dimensions: | 41 × 24 × 27 mm | * Split core * Safe operation * Mini in size * Very easy mounting * Wide inner window ===== General description ===== The CT1-E-50 split core current transformer is designed for fast and easy installation. The split core design permits non-contact current measurements through magnetic field induction without requiring that the primary wire be taken off line and disconnected for CT installation. This method permits a safer easy and portable current measurement. An internal precision burden resistor across the secondary winding of the CT provides a safe low voltage output and permits safe opening of the secondary circuit. ===== Technical specifications ===== |< 50% 50% >| | Frequency | 50-60 Hz | | Rated current | 50 A | | Accuracy | ±1% from 20% to 120% of rated current | | Phase angle | less than 2 degrees at 50% of rated current | | Insulation voltage | 600 VAC | | Maximum primary voltage | 5000 VAC (insulated conductor) | | Dielectric strength | 2.5 kV/1mA/1min | | Operating temperature | -15 to 60°C | | Operating humidity | < 85 % | | Case material | PC/UL94-V0 | | Bobin | PBT | | Core | Permalloy | | Internal structure | Epoxy | | Leads | UL 1015, Twisted pair, 22 AWG |
