General Description
- Voltage rating of 0.72kV
- Impulse rating of 10kV BIL
- Cast in high dielectric strength Cycloaliphatic grey epoxy
- Suitable for higher voltage installation over bushing or insulated cable
Applications
The POCZR series current transformers are designed for outdoor service, for ambient temperatures between -50°C to +70°C. Applications include:
- Protective relay applications
- Leakage current measurement
- Ground fault protection
Construction
- Annealed toroidal cores of high grade electrical steel
- 200°C enamel coated copper magnet wire
- Secondary turns uniformly distributed around the core for each tap position
- #10-32 Brass secondary terminals are standard, other options available
- Prominent polarity markings
- Secondary terminal box supplied with most models
Voltage Class -0.72kV
Impulse (BIL) - 10kV
Frequency – 60Hz
Thermal Withstand – up to 160 x Rated Current (1 sec.)
Mechanical Withstand – up to 270 x Rated Current (6 cycles)
Continuous Current Rating Factor – up to 2.0 @ 30°C
Note: For low ratio current transformers (250-5A and less), the ratio error at rated current may exceed the limit specified by industry standards.
