Himalayal Corporation Limited products

The AC test transformer are especially designed for testing high voltage products and components, such as power cables, transformers, gas-insulated switchgears, generators, bushings, arresters and other HV apparatus. They are mainly used for voltage withstand insulation test system. These systems are particularly suited for tests requiring stable voltage even if the load changes under voltage (corona, wet & pollution tests) or when the load is inductive {inductive voltage transformers) .The AC test transformer have two types: insulated cylinder type and metal tank type.

Over Current Ability: Continuous working for 3 minutes under 120% rated current, then thermal damage or distortion of the winding shall not be occurred.

Short-circuit capability: test transformer discharge to test object via damping resistor under transient state capacitance, the short circuit current reach 2 time output, continue 8 cycle will not cause damage to transformer winding or cause any mechanical deformation. Equip upper and lower position limited function. Weight 15kgs.

Operation Time: working 60 minutes under 100% rated voltage; Continuous working allowed at 80% rated current & voltage. Short-circuit capability: test transformer discharge to test object via damping resistor under transient state capacitance, the short circuit current reach 2 time output, continue 8 cycle will not cause damage to transformer winding or cause any mechanical deformation. Equip upper and lower position limited function. Weight 15kgs
