T&R KV100-100 MK3 High Voltage AC Test System
The KV100-100 MK3 Test System serves as a high-power, high-voltage AC test set designed specifically for insulation testing. This system caters equally to both the development and routine testing of electrical insulation systems and plant.
The equipment comprises a control unit and a separate oil-filled high-voltage transformer, connected by 5-meter supply and control cables. The control unit incorporates a comprehensive range of facilities for control, metering, and protection. As a standard feature, the system includes secondary tap metering to ensure accurate voltage measurement. The output voltage and current are visibly displayed on large, linear analog instruments. Additionally, a variable electronic trip allows users to set the trip current within the range of 10% to 110% of the rated output.
For mobility, the high-voltage transformer is housed within an oil-filled steel tank equipped with swivel castors. The HV output utilizes a low-discharge oil-filled bushing. Notably, the KV100-100 MK3 Test System is equally adept at testing capacitive, resistive, and inductive test objects.
To safeguard the units' output, variable electronic trips monitor the output current, supplemented by a fixed over-current trip on the primary side of the output transformer. The adjustable trip feature permits fine-tuning in 10% increments between 10% and 110% of the rated output current. Moreover, fuses provide protection for the input and control supplies. An earth terminal is present on the transformer, necessitating connection to a low-impedance local earth.
