Product Description TEST-901 With timer High Precision 1000A PRIMARY CURRENT INJECTION TEST SET for CIRCUIT BREAKERTEST-901 1000A primary current injection test set adopts ARM Chip to control its output process and large capacity of toroidal transformers. TEST-9011000A primary current injection test set is equipped with LCD display and current meter; it can show primary current value, second current value, turn ratio and the action time. Packing is used as aluminum alloy body with PC panel. TEST-901 primary current injection test set is mainly applied to CT turn ratio testing in the power system and contact resistance test which need large current.1. test current transformer2. test circuit breaker3. test high voltage switchPrimary current injection testing is utilised in high current/high voltage scenarios found at large electrical installations such as substations. A large current (between 100A and 20,000A depending on system specifications and test requirements) is injected directly on the primary side of the electrical system such as a circuit breaker. The objective of the test is to identify how the system operates under various levels of current load.Primary injection testing is suitable for testing over-current trip relays attached to a circuit breaker. By injecting the current into the system we can measure if the breaker will trip or fail, and how long the current is live before the circuit is broken.Circuit breakers can go long periods of time without activation, and failure at the moment of activation can cause catastrophic damage to the electrical system. Circuit breaker testing with primary current injection on a breaker that has not triggered in some time is the best way to recreate the real operating conditions of a current spike.PARAMETERSElectrical parameters Accuracy±0.5%Power Supply(AC)220V±10%·25A, 50Hz/60Hz or110V±10%·50A, 50Hz/60HzCurrent Output (AC)1000A·5V or 500A·10VCapacity5KVAThe current output waveform distortion≤5%Dual protectionoverload electronic protection and software protectionPrimary current Range0-1100AResolution0.1AAccuracy<0.5%Secondary measurement Range0-6AResolution0.001AAccuracy<0.5%Current duration 1000A range1000A 2-3minutes500A 3-6minutes500A range500A 2-3minutesWith timer Range0.0001~999.99SResolution0.001SAccuracy<0.5% ±5 wordsMechanical parameters Dimensions (W×D×H) (mm)430×260×260Weight(kg)25Environmental conditions Temperature-10°C to 40°CRelative humidity≤80%Selection guideMODELACCURACYPRIMARY CURRETNTAMMETER(0-6A)TIMERPOWERINJECTION CURRENT TIMEDIMENSION(W×D×H)(mm)WEIGHTREMARKTEST-9010.50%0-1100AYESYES5KVA1000A: 2-3min;500A:3-6min430×260×26025KGIntegrated structureTEST-9020.50%0-2200AYESOPTIONAL12KVA2000A:2-3min;1000A:3-6min360×300×295 and 320×300×30035KG+15KGFission structureTEST-9030.50%0-3200AYESOPTIONAL15KVA3000A: 2-3min;1500A:3-6min410×370×320 and 360×320×30048KG+25KGFission structureTEST-9050.50%0-5500AYESOPTIONAL25KVA5000A:2-3min;2500A:3-6min480×450×420 and 390×340×47068KG+55KGFission structure
