35KV 10000A Limit DC Component Resistance Device for High Voltage Testing
Operating Condition:
1. Indoor and outdoor application;
2. System frequency: 50Hz or 60Hz;
3. Altitude: Not over 3500m (Please specify when ordering because high elevation leads to poor heat
dissipation);
4. Ambient condition: -20℃~+70℃, 95%RH at the most;
5. Wind pressure: Not over 700MPa (equals to wind speed of 34m/s);
6. Seismic intensity: Lower than Class VIII as demonstrated by the China Seismic Intensity Scale;
7. Environmental pollution level: Class IV or lower;
8. Surroundings: No flammable or explosive objects, no corrosive gas or conductive dust;
9. Our neutral grounding resistor will generate heat during work, thus leading to a big temperature rise. So,
there should be certain space around this electrical device during installation and operation.
Benefits:
* Eliminate phase-to-ground arc-flash incidents;
* Eliminate transient overvoltages;
* Reduced point-of-fault damage;
* Can provide continuity of service during a ground fault;
* Modularized resistance: standardization and modularization is realized for various resistance; through tandem and parallel connection, any combination can be materialized to meet the requirements of clients for through-current capability, voltage and resistance etc, and it is easy to make replacement.
