Applications:

KDSL-82-500A short-time overcurrent tester is applicable to various power and industrial site environments, mainly including:
Substation and power distribution room: used for transformation ratio and polarity verification after installation of current transformer (CT) and short-time overcurrent test of relay protection device;
Power construction and maintenance site: quickly verify CT performance before equipment is put into operation or during maintenance to ensure accurate and reliable protection system;
Electrical equipment manufacturer and laboratory: carry out ex-factory test, metering verification or R&D test of transformer;
Railway, petrochemical, metallurgical, mining and other enterprise owned power stations: used for regular detection and troubleshooting of internal power supply and distribution systems.

The equipment conforms to GB6587.1-86 Group III standard, and can operate stably in indoor and outdoor environment of - 10 ℃ -+50 ℃, humidity ≤ 90% (non-condensing) and altitude below 1500m. It supports AC 220V single-phase power supply and is compact and easy to carry. It is especially suitable for mobile operation and site use with limited space.
