Universal primary injection test set for substation assets
Electrical tests on power transformers, current transformers, voltage transformers, rotating machines, grounding systems, lines and cables, and circuit breakers can be performed with the TEST-901.
The patented TEST-901
primary injection test system replaces several individual testing devices. This reduces the costs for training and transport, and cuts down testing time. Therefore, the TEST-901
is the ideal test set for substation asset commissioning and maintenance.
Applications
Grounding systems
Ground impedance
Step and touch voltages
Circuit breakers
Contact resistance
Current transformers (CT)
Ratio, burden and polarity
TEST-901 primary current injection test set adopts ARM Chip to control its output process and large capacity of toroidal transformers. It is equipped with LCD display and current meter; it can show primary current value, second current value, turn ratio and the action time. Packing is used as aluminum alloy body with PC panel. TEST-901 is mainly applied to CT turn ratio testing in the power system and contact resistance test which need large current.
