YOKOGAWA 03021729 AC Ammeter Transformer Rated

YOKOGAWA 03021729 AC Ammeter Transformer Rated Specifications:

• Accuracy: All DC and AC iron-vane; ±2% of full-scale, AC rectifier type; ±3% of full scale (with 60 Hz sine wave at 25º C). When standard 60 Hz iron vane ammeters are used at the extreme limits of 20 or 400 Hz, additional error (approx. .75%) may be experienced. Expanded-scale voltmeters; ±.5% of full scale value.
• ANSI Specification: All meters meet ANSI Specifications C-39.1.
• Overload: Voltmeters (AC and DC) - 50% momentary, 20% sustained. Ammeters (AC and DC) momentary: 10 times the rated current for 10 consecutive intervals of .5 second with a 1 minute interval between successive applications; sustained: 20% for six hours.
• Scale Data: 90 degree rotation.
• Scale Length: Size Horizon Line 1 1/2” 1.50” 2 1/2” 2.06” 3 1/2” 2.88” 4 1/2” 3.93”
• Insulation Level: All meters (except 1 1/2”), 2600 VRMS Hi-pot, 1 1/2”-1500 VRMS Hi-pot.
• Burden Data: AC ammeter-5 amps, 0.5 va max. 0.5 power-factor lagging, @60 Hz. AC Voltmeter-unity power factor.
• Response Time and Overshoot: Response time: 3 seconds (max.) for 2 1/2”, 3 1/2”, 4 1/2” size for microammeters: 2 seconds (max.) for all other DC ratings, and 2.5 seconds (max.) for AC ratings. Maximum of 40% overshoot.
