TPT9000 Transformer Polarity Tester

The TPT9000 is used for determining the correct polarity of current and voltage transformers. The TPT9000 automatically detects if the transformer has been connected incorrectly. The set also includes a proving unit to check the correct operation of the unit in the field.

The TPT9000 is designed to be used on ‘dead’ systems (i.e., no externally supplied voltages are present on the test object). Do not connect the TPT9000 to a live system. Always check that the power to the device under test is off. and the circuit is isolated before making any connections.

Environment
The TPT9000 is designed for use in industrial and electrical substation environments.
Maximum altitude: 2000m
Temperature:
operating 0°C to 45°C
storage -20°C to 60°C
Relative humidity: 90% noncondensing
Protection rating: IP20 in use

Supply requirements
The TPT9000 requires a single PP3 9V battery to operate. The battery level is automatically monitored, and the device will not perform a test if the battery voltage is below a useable level.

Test Leads
600V CAT IV fused test leads terminated in shrouded 4mm connectors.

Overload protection
Each of the test leads must be fitted with a F500mA HRC fuse. This must be replaced with a fuse of the same type.
