We provide Three Phase Isolation Transformer in variegated specifications to meet diverse applications.   Standards : The power conditioning system is designed in accordance with applicable portions of the following standards NEMA TP 1-2002 Dry Type Distribution Transformer Efficiency Standards American National Standards Institute (ANSI C57.110 & C62.41-1991) Institute of Electrical and Electronic Engineers (IEEE 519-1992) National Fire Protection Association (NFPA) 70, National Electrical Code (NEC) Federal Information Processing Standards Publication 94 (FIPS Pub 94) UL Listed to Standard 1561 C-UL listed to CSA Standard C22.2, No. 47-M90  Input Specifications : Nominal AC input voltage ratings: 600 VAC, 480 VAC, 240 VAC or 208 VAC, 3 phase for transformers below 225kVA,and 600 VAC or 480 VAC, 3 phase for transformers 225kVA and above. All are designed with sufficient margin tosustain a constant input of +10% without saturation. The nominal operating frequency: 60 hertz + 3 hertz. The power conditioning system’s primary is configured in a three phase delta. Transformers below 500kVA include full capacity taps at 2½ % increments, two (2) above and four (4) below the nominal voltage tap. 500kVA transformers include full capacity taps at 2½ % increments, one (1) above and two (2) below the nominal voltage tap. Energizing inrush current will not exceed 10 times the full load input current for ½ cycle.  Output Specifications : Output Voltage : Sinusoidal with no flat topping when high crest factor (3.0 : 1), non-linear loads are present at the output. Audible Noise Measured at 1 Meter from the Unit : ≤ 50dBA for 15 KVA to 112 KVA ≤ 55dBA for 150 KVA to 225 KVA ≤ 60dBA for 300 KVA to 500 KVA Electrostatic Shielding : Incorporates two, or an optional three, solid copper foil electrostatic shields which minimize inner winding capacitance, transients, and noise coupling between primary and secondary windings. Common Mode Noise Attenuation : 126 dB with two shields, or 146dB with optional three shields. Transverse Mode Noise Attenuation : 3 dB down at 10kHz, decaying 20 dB per decade. Efficiency : 98% typical and meets NEMA TP 1-2002 dry type transformer efficiency standards on models 15kVA and above. The power conditioning transformer is designed to achieve NEMA TP 1-2002 Table 4-2 efficiencies listed below under a K-4, K-7, or K-13 non-linear load at or between 35% to 50% load and at an operating temperature of 75 degrees C. KVA Efficiency : 15* 30 97.00% 97.50% 50 97.70% 75 98.00% 112 98.20% 150 98.30% 225 98.50% 300 98.60% 500 98.70%   *15kVA model efficiency applicable to K4 and K7 loading only.  Optional TVSS : Incorporates a fused (with front panel mounted, blown fuse lamp indicator) 3 phase, secondary connected, 6 mode spike suppression network. The TVSS is comprised of high energy metal oxide varistors with less than a 5 nanosecond response time and a maximum peak current handling capability of 40,000 amps (8x20μsec) per mode. The suppression network system will remain functional when subjected to ANSI/IEEE C62.41 Category B-3 waveforms. The spike suppression network increases the transverse mode noise attenuation to 3 dB down at 10kHz, decaying 40 dB per decade.  Main Transformer : Transformer Windings : All copper conductor construction, with separate primary and secondary, isolated windings. The transformer conforms to NEC article 250, that specifies a separately derived power source. The neutral conductor is sized for 200% of the ampacity of the phase conductor. Terminals are provided for isolated three phase output conductors, neutral conductor and ground. All leads, wires and terminals are labeled to correspond with the circuit wiring diagram.
