Advanced Cable Testing & Diagnosis
Diagnostics of medium and high voltage cables provides the opportunity for early detection of vulnerabilities, allowing preventative maintenance work to be carried out before the cable fails in service.
We have Most Advanced Cable Diagnosis Instruments with both VLF and DAC standard compliance up to 33 KV Class.
PD diagnostics can be carried out simultaneously with the TD diagnostics. This saves time and prevents pre-conditioning of the cable by the first of two sequential tests.
We have identified more than 200 cables prior to fail and saved substantial cost and more important integrity of supply of power.
Battery Capacity with Advanced Load Tester
The capacity test is carried out following the battery testing standards: IEEE 450-2010, IEEE 1188-2005, IEEE 1106-2015, IEC 60896-11/22, and other relevant standards.
We can do with following discharge modes:
- Constant current,
- Constant power,
- Constant resistance
