Dielektrimeter für Isolieröl YDJ

DCHochspannungtragbar

Product Introduction
The YDJ Pointer 5kVA Oil-Immersed AC Test Transformer is a traditional high-voltage testing device that utilizes oil insulation to deliver stable AC withstand voltage tests on electrical equipment. With a 5kVA capacity, it is well-suited for testing medium-sized apparatus such as transformers and cables. The pointer-style analog interface provides clear, real-time readings of voltage and current. The oil-immersed design ensures effective heat dissipation and reliable insulation performance, making this classic tester an ideal choice for industrial and laboratory applications that demand robust dielectric strength validation.
