Product catalog summary

Specifications:
The document details the specifications for GE Grid Solutions Models PTG4-1-75 & PTG4-2-75 indoor voltage transformers. These transformers are designed for medium voltage applications and comply with ANSI/IEEE C57.13 standards. They are classified by U.L. according to IEC 44-1. The accuracy class is specified as 0.3 WXMY 1.2ZZ at 100% rated voltage with a 120 V based ANSI burden, and 0.3 WXMY, 1.2Z at 58% rated voltage with a 69.3 V based ANSI burden. The frequency is 60 Hz, and the maximum system voltage is 9.52 kV with a BIL of 75 kV.

Thermal Rating:
The thermal rating is 1,500 VA at 30°C ambient and 1,000 VA at 55°C ambient. The approximate weight of the unfused transformer is 85 lbs.

Regulatory Approvals:
The transformers are approved for revenue metering in Canada by Industry Canada, Approval No. AE-0429.

Design Features:
The transformers are unfused with two bushings. Primary terminals are 1/4-20 brass screws with washers, and secondary terminals are No. 10-32 brass screws. The core and coil assembly is vacuum encapsulated in polyurethane resin. A test card is provided with each unit.

Installation Recommendations:
Recommended minimum spacings are 1.00” unit to unit and 4.50” HV to ground in air. These spacings are for guidance, and users should set appropriate values for specific conditions. The document advises against using two fuse transformers for Y connections and provides guidelines for safe operation and connection practices.

Additional Notes:
The document includes a circle diagram and notes on fuse clip specifications. It emphasizes that system line-to-line voltage should not exceed the transformer maximum system voltage level.

Circle Diagram Recommended Minimum Spacings A = Unit to Unit = 1.00” minimum. B = HV to Ground in air = 4.50” minimum. Recommended spacing are for guidance only. User needs to set appropriate values to assure performance for high potential test, impulse test, high humidity, partial discharge, high altitude, andother considerations like configuration. (a) Two fuse transformers should not be used for Y connections. It is preferred practice to connect one lead from each voltage transformer directly to the neutral terminal, using a fuse in the line side of the primary only. By using this connection...
