TEST-905 5000A 25KVA CAPICITY PRIMARY CURRENT INJECTION TEST SYSTEM FOR POWER TRANSFORMER TESTING
5000A 25KVA CAPICITY PRIMARY CURRENT INJECTION TEST SYSTEM FOR POWER TRANSFORMER TESTING
TEST-905 primary current injection test system adopts ARM chip to
control the output process and large capacity of toroidal
transformer. It is equipped with LCD screen display current meter,
also showed primary current value, secondary current value, turn
ratio and the phase shift. Aluminum alloy body with PC panel
component the shell.
TEST-905 is mainly applied to test CT turn ratio and polarity in
the power system, the contact resistance, high voltage circuit
breaker protection test and high voltage generator test etc, which
need large current on-site or in the lab.
Primary current injection testing system 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 system 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.
Primary current injection testing and breaker testing These tests require high currents and the ability to measure very short duration, current flow. INGVAR has been designed especially to meet these needs. No extra contacts are needed to measure the operating time of a low-voltage breaker. Testing stops at the instant when the main breaker contacts open to interrupt the current. Output current initiation is synchronized with the currents zero-crossover point to ensure good repeatability and minimized DC offset.
Testing current transformers For turns ratio testing, the primary current and either the secondary current or the turns ratio are displayed simultaneously. Since the turns ratio is displayed directly as the nominal value (1000/5 for example), no further calculation is needed. Burden of secondary circuits can be measured and presented in VA.
Polarity testing The currents phase displacement is shown, and the polarities of the outputs are clearly marked.
Heat runs INGVAR is ideal for performing heat runs. Current can be applied continuously or through programmable intervals. The times can be shown in minutes and hours which facilitates long-term testing capability. Automatic reclosers and sectionalizers INGVAR can also be set to test circuit breakers with reclosing relays. Operating limits, partial times, total times and the number of operations before lockout can be measured. User-selectable reclosing sequences can be programmed for testing sectionalizers.
Testing integrity of safety-ground devices One way to test safety-ground devices is by injecting current through the safety-ground and measure the voltage drop to get the impedance.
