Type test is performed on transformer to check design perimeters of transformer.
True
False
True
A type test is conducted on a prototype transformer to verify its design specifications and ensure compliance with national or international standards (e.g., IS 2026 or IEC 60076). It is meant to prove that the design meets the thermal, electrical, and mechanical requirements under rated conditions.

During a type test, a sample unit is subjected to severe conditions such as lightning impulse tests, temperature rise tests, and short-circuit withstand tests. These tests validate the design parameters, such as insulation coordination, winding geometry, and core losses, ensuring the design can handle operational stresses throughout its service life.
Type tests are performed once on a 'prototype' design, not on every manufactured unit.
Essential for establishing the design's reliability, efficiency, and safety margins.
Tests include Temperature Rise, Lightning Impulse, and Short Circuit Withstand tests.
If design changes significantly, the type test must be repeated.
Ensures the theoretical design meets real-world physical stress requirements.
Prevents mass-production of faulty or under-designed transformer models.
Destructive or near-destructive in nature (e.g., short-circuit tests).
High cost and time-intensive process.
Initial design validation for new transformer series.
Mandatory requirement for government and utility-grade tenders.
Routine tests are performed on EVERY transformer manufactured, whereas type tests are performed on a representative sample.
Option B is False because type tests are fundamentally different from routine tests that are performed on every production unit.
A is correct тАФ Type tests are specifically conducted on a prototype unit to validate the design calculations and performance against specified standards.
Always remember the mnemonic: Type = Prototype (once), Routine = Regular (every), Special = Specific (as per request).
