We are a reputed firm engaged in offering precision-engineered Three Phase Isolation Transformer. It is a continuous duty rated, 600 volt class, convection cooled, dry type, isolation transformer to support harmonic rich non-linear loads while maintaining safe operating temperatures. This transformer includes superior transverse and common mode noise attenuation. Designed as per NEMA TP 1-2002 dry type transformer efficiency standards, our transformer is acknowledged for high performance and reliability. 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.
