TV60 DAC Test and Diagnosis System 60 kV, up to 36 kV cable systems, China TV60 DAC Test and Diagnosis System 60 kV, up to 36 kV cable systems Manufacturers, Suppliers, Factory - Tanbos Electric Technology (Hangzhou) Co.,Ltd.

Introduction

The TV60 is a DAC (Damped AC Voltage) test set with a peak voltage of 60 kV. The test set can be used for

quality control on newly installed, repaired or service-aged MV cable systems with reliable results and an

appropriate assessment of the condition of the cable insulation as well as of the accessories. This is the key

to successful operation of the distribution and transmission networks.

DAC voltage test and diagnostic measurements provide for reliable detection of poor installation, failures

due to inappropriate laying, failures in accessories or deterioration in cable insulation due to aging. It allows

much more than a simple “go or no-go” decision. DAC testing is an advanced maintenance tool which

supports asset management and grid operation as well.

Applications

After-laying testing of newly installed or repaired cable systems
Routine testing and diagnostics for assessment of service-aged cables
PD monitored voltage withstand testing and non-destructive diagnostic testing
Comprehensive PD measurement capabilities according to IEC 60270, IEC 60885-3, IEEE 400.3

Time-saver at your service for cable diagnostics：

Connect — Automatic — Inspect

The on field test is very simple, after the connection between TV60 and cable is completed, the operating

software will guide you through the entire process.

Connect: After the necessary inspections and pre-tests are completed, only need few connections about

DAC test.

Automatic: Second step is just follow the steps of operating software, only need to input some necessary

parameters of tested cable, others system will complete it automatically.

Calibration Automatic test
